This catalog is a compilation of observational data concerning 1,159 stars of type Be and is part of a larger effort to produce the {\em Catalogue of Stellar Groups}, a list of stars grouped according to spectral peculiarities. Listed for each star are identifications, position, {\em V}, {\em U-B}, {\em B-V}, radial velocity, MK spectral classification with the dispersion used, rotational velocity, and several flags indicating miscellaneous information. The catalog is in two files: the first lists the identifications, coordinates, photometry, radial velocity, and MK spectral type; the second includes additional identifications, rotational velocity, and miscellaneous flags. The present document describes the overall file structure and the individual data fields. \end{abstract} \section{Introduction} {\bf A copy of this document should be distributed with every copy of the computer-readable catalog.} \subsection{Description} The {\em \cat} (\abbr; \prefp) is a compilation of data concerning stars of type Be. For the purposes of this compilation, a Be star is defined as ``a non-supergiant B star which showed emission in one Balmer line at least once'' (\prefp). Stars without published MK spectral types have been excluded except for 132 stars from Bidelman and MacConnell (1973), who used the above definition but included no spectral types. 1,159 stars are included in this list. The catalog is in two files. The first file lists the following information for each star: \begin{itemize} \item Identifications: DM number or CSI key, Be star number, and HD number \item Equatorial and galactic coordinates \item {\em V}, {\em U-B}, {\em B-V}, and associated quality indices \item Radial velocity and quality index \item MK spectral type with dispersion used or quality index \end{itemize} \noindent The second file repeats the identifications and MK spectral types of the first file in addition to the following information: \begin{itemize} \item Rotational velocity and probable error \item Two flags indicating whether the star is a visual or spectroscopic binary \item Three flags indicating in what other photometric system(s) the star has been measured \item Star name and variable star name \end{itemize} \subsection{Reference} \begin{references} \item Jaschek, M. and Egret, D. 1982, {\em IAU Symposium No. 98, ``Be Stars''}, eds.

Table \ref{t:sumtab} gives the machine-independent tape-file attributes. All records are of fixed length. The first file lists the main catalog data (Table \ref{t:cattab}), and the second file lists the additional information (Table \ref{t:addtab}). Detailed descriptions of each file are given below. {\bf Quotations in any of the following descriptions come from \cat\ unless otherwise noted}. \begin{table}[htbp] \centering \begin{tabular}{|c|l|c|c|r|} \hline \multicolumn{5}{|c|}{\cat\/ (\prefp)} \\ \hline & & Record & Record & \multicolumn{1}{c|}{Number of} \\ File & \multicolumn{1}{c|}{Contents} & Format & Length & \multicolumn{1}{c|}{Records} \\ \hline 1 & Catalog & Fixed & 126 & 1,159 \\ 2 & Additional Info. & Fixed & 96 & 1,159 \\ \hline \end{tabular} \caption{Summary Description of Catalog Files} \label{t:sumtab} \end{table} \subsection{Catalog (File 1 of 2)} \label{s:cat} This file lists the main catalog data. \begin{table}[htbp] \centering \begin{tabular}{|c|c|c|l|} \hline & & Suggested & \\ Bytes & Units & Format & \multicolumn{1}{c|}{Data} \\ \hline 1-11 & & A11 & DM/CSI number \\ 12 & & 1X & Blank \\ 13-21 & & A9 & Be star number \\ 22-28 & & I7 & HD number \\ 29 & & A1 & HD suffix \\ 30-32 & hr & I3 & Right ascension \\ 33-35 & min & I3 & \\ 36-40 & sec & F5.1 & \\ 41 & & A1 & Coordinate flag \\ 42 & & A1 & Declination sign \\ 43-44 & deg & I2 & Declination \\ 45-47 & arcmin & I3 & \\ 48-50 & arcsec & I3 & \\ 51-52 & & 2X & Blank \\ 53-58 & deg & F6.2 & Galactic longitude \\ 59 & & 1X & Blank \\ 60 & & A1 & Galactic latitude sign \\ 61-65 & deg & F5.2 & Galactic latitude \\ 66-71 & mag & F6.2 & {\em V} \\ 72 & & A1 & {\em V} uncertainty \\ 73 & & A1 & {\em V} flag \\ 74 & & A1 & {\em V} source \\ 75 & & A1 & {\em V} quality \\ 76-77 & & 2X & Blank \\ 78-82 & mag & F5.2 & {\em B-V} \\ 83-84 & & 2X & Blank \\ 85 & & A1 & {\em B-V} quality \\ 86-87 & & 2X & Blank \\ 88-92 & mag & F5.2 & {\em U-B} \\ 93-94 & & 2X & Blank \\ 95 & & A1 & {\em U-B} quality \\ 96-102 & km/s & F7.1 & Radial velocity \\ 103 & & 1X & Blank \\ 104 & & A1 & Radial velocity quality \\ 105 & & 1X & Blank \\ 106-108 & & A3 & Dispersion \\ 109 & & 1X & Blank \\ 110-126 & & A17 & MK spectral type \\ \hline \end{tabular} \caption{Catalog Record Format} \label{t:cattab} \end{table} \begin{definition}{20ex} \item[DM/CSI number] Durchmusterung numbers are indicated by `BD'', ``CD'', or ``CP'' in bytes 1-2, followed by the DM number in the form $\pm$ZZNNNNN, where ZZ is the declination zone and NNNNN is the sequential number of the star within the zone. Numbers from the {\em Catalogue of Stellar Identifications} (CSI; Ochsenbein {\em et al.} 1981) are indicated by blanks in bytes 1-2, followed by the CSI number in the form $\pm$ZZ$-$NNNNN, where ZZ is the declination zone and NNNNN is the sequential number of the star within the zone. \item[Be star number] Star number from one of the following catalogs: \begin{definition}{8ex} \item[MWC] Merrill, P. W. and Burwell, C. G. 1933, {\em Astrophys. J.}, {\bf 78}, 87. \\ Merrill, P. W. and Burwell, C. G. 1943, {\em Astrophys. J.}, {\bf 98}, 153. \\ Merrill, P. W. and Burwell, C. G. 1949, {\em Astrophys. J.}, {\bf 110}, 387. \item[AS] Merrill, P. W. and Burwell, C. G. 1950, {\em Astrophys. J.}, {\bf 122}, 72. \\ Miller, W. C. and Merrill, P. W. 1951, {\em Astrophys. J.}, {\bf 113}, 624. \item[Henize] Henize, K. G. 1976, {\em Astrophys. J. Suppl. Ser.}, {\bf 30}, 491. \end{definition} \item[HD number] Number from the {\em Henry Draper Catalogue} (Cannon and Pickering 1918-1924). The suffix is a single-character code. ``A'' indicates the first component of a multiple system; ``/'' indicates that the HD number is the first of two consecutive HD numbers for a multiple system in which only one spectrum is observable. \item[Equatorial coord.] Equinox 1950.0. The {\bf coordinate flag} is ``:'' to indicate uncertainty in the coordinates. \item[V uncertainty] ``:'' if the magnitude in bytes 66-71 is uncertain. D. Egret (1987) notes that in general this ``flags a magnitude not given in the standard {\em UBV} system.'' \item[V flag] ``V'' indicates the star is variable; ``D'' indicates that the magnitude in bytes 66-71 is the integrated value for both components of a binary system. \item[V source] ``*'' if {\bf\em V} is from the CSI; otherwise, the value is from Nicolet (1978). \item[V quality] In all but one case, a single-digit integer indicating the quality of the {\em V} magnitude. The numbers range from 1 (poor) to 4 (very good). Record number 82 has the undefined character ``E'' in this field. \item[B-V quality] In all but one case, a single-digit integer in the range 1 (poor) to 4 (very good). Record number 82 has the undefined character ``E'' in this field. \item[U-B quality] In all but one case, a single-digit integer in the range 1 (poor) to 4 (very good). Record number 82 has the undefined character ``E'' in this field. \item[Radial velocity] These values are taken from Wilson (1953) and Evans (1967), or from Abt and Biggs (1972) or Barbier (1975) if no quality follows. \item[Rad. vel. quality] Single character in the range A-F, as listed in Evans (1967). ``A'' represents the best quality. \item[Dispersion] Dispersion used to determine the {\bf MK spectral type}, or a quality for the spectral type. When byte 108 contains ``/'', the {\bf MK spectral type} comes from Jaschek (1978) and bytes 106-107 indicate the dispersion used: \begin{definition}{5ex} \item[P] Prism \item[OP] Objective prism \item[G] Grating \end{definition} When this field contains a quality number, the {\bf spectral type} is from the {\em Michigan Spectral Survey} (MSS; Houk and Cowley 1975, Houk 1978) and this field contains the spectral type quality, using the following codes: \begin{definition}{5ex} \item[1..4] Quality in the range 1 (very good) to 4 (poor) \item[+] The {\bf MK spectral type} was found in the literature and not derived by N. Houk for the MSS. \item[X] Overlap \end{definition} When this field is blank, the {\bf MK spectral type} came from a source other than Jaschek (1978), Kennedy (1980), or the MSS. These sources include the following: \begin{references} \item Andersen, J. and Nordstr\"{o}m, B. 1977, {\em Astron. Astrophys. Suppl.

The original tape consisted of two text files in a format similar to that described above. Eight bytes containing the file identifier were removed from the beginning of every record in both files, and leading and trailing blanks were trimmed to reduce the record size from 140 bytes in both files to 126 bytes in the first file and 96 bytes in the second file. In the first file, the {\bf\em V} magnitudes were shifted one byte to the left to allow the {\bf\em V} {\bf uncertainty} flag to be separated from the numeric field. In the second file, the left parenthesis sometimes occurring within the {\bf rotational velocity probable error} field was moved outside that field to enable the error field to be read with the indicated FORTRAN format. A FORTRAN program was run to check the validity of each field according to its data type and value. As a result, several non-numeric values were discovered in numeric fields of records in the first file. The character ``:'' found in the {\bf\em V} {\bf quality} field of records number 568, 753, and 827 was moved to the {\bf\em V} {\bf uncertainty} field. Record number 82 had the undefined character ``E'' in all three {\bf quality} fields ({\em V, B-V,} and {\em U-B}). This record was left unchanged. \subsection{References for the Documentation} \begin{references} \item Abt, H. A. and Biggs, E.
