Description:
The catalog (RAFGL) contains the results of extensive verification and
photometric studies of AFGL sources performed since the publication of
"The AFGL Four Color Infrared Sky Survey: Catalog of Observations at
4.2, 11.0, 19.8, and 27.4 micrometers" (AFGL, Price and Walker 1976)
as well as recent survey measurements with larger instruments.
Improved positions and more extensive photometry have been provided by
ground-based searches for the RAFGL objects and questions about
unconfirmed sources from early investigations of the AFCRL Infrared
Sky Survey (Walker and Price 1975) have, for the most part, been
resolved. Many of the spurious sources were eliminated from the AFGL
catalog in the reanalysis by including a rescan confirmation criterion
in addition to the signal-to-noise gate used for the AFCRL catalog.
The RAFGL is a revision of AFGL to include more accurate information
and to provide identifications and improved positions for unidentified
AFGL sources.

Note (2): when the error is absent, the following code indicates
that a magnitude is derived from another source:
C CIO (Gezari et al. 1982; see cat. II/209)
W Grasdalen et al. 1983ApJS...53..413G 1983ApJS...53..413G
M Ney and Merrill 1980
Note (3): Spectral type, mostly from association of the survey source
with an object in the 2 micron Sky Survey (TMSS, Neugebauer and
Leighton 1969, see Cat. II/2). Spectral types were also taken from
Bidelman (1980PW&SO...2..183B 1980PW&SO...2..183B, and private communication),
Buscombe (1981), Kukarkin et al. (1969-1976, 3rd Gen.Cat.Var.Stars
and first Supplement), and Kleinmann et al. (1981).
Note (4): AFGL numbers < 3200 identify sources in the AFCRL and AFGL
catalogs. Sources originally in the supplemental catalog (Price 1977)
are identified by an S in byte 78. The 624 detections from the SPICE
and FIRSSE flights are given by right ascension beginning at 5001,
while new entries in the "revised" supplemental catalog (file supp.dat)
start at 6001S.
Note (5): IRC catalogue is II/2; its extension (Neugebauer 1971)
is indicated by an "E" in byte 86.
Note (6): Comments on source identification:
The class of object is given if the association is with an NGC source,
or a galaxy type may be given. Sources measured to be extended ≥ 5
arcminutes are designated by "EO", while sources of marginal extent
are indicated by "E?".
Note (7): A three-byte code outlining the observational record for the
entry. The three bytes have the following meanings:
Byte#1: Pertains only to previous AFGL sources.
"C" indicates that the source was detected in a common color
on a SPICE or FIRSSE flight. If this is not the case, the
maximum number of times the source was seen in a common color
as listed in the AFGL catalog is given.
Byte#2: Describes observation within a SPICE or FIRSSE flight.
"2" means that the source was seen twice in a common color
on the same flight; "0" denotes no common color confirmation.
If the object was rescanned but not confirmed, an asterisk (*)
designates that the rescan region contained optical
contamination or has a calculated S/N < 3.
A question mark (?) means that the calculated S/N was between
3 and 5 on rescan or the confirming detector was at the end of
the array.
An "S" or "F" means that the source was only scanned once on a
SPICE of FIRSSE flight, respectively.
Byte#3 Denotes flight-to-flight observations. The asterisk (*) and
question mark (?) have the same meanings as for the second byte.
A number means that the entry is a combination of a FIRSSE and
SPICE measurement:
"2" a common color with values within 60 percent
"3" a common color with values > 60 percent of each other
"4" no common color

History:
* From Wayne H. Warren, May 1984:
"The Revised AFGL Infrared Sky Survey Catalog" was received on
magnetic tape (7-track BCD coded at 800 bpi) from Dr. S. D. Price on
15 November 1983. The following modifications were made to both files
of the catalog in order to conserve storage space and to archive the
files in a standard character code:
1. The BCD (O26 punch) coding was converted to EBCDIC, code which
is readily transformed to ASCII if desired.
2. The infrared magnitudes were inhomogeneous in format. Minus
signs were moved and preceding zeros added so that all numbers
are identical in their respective fields.
3. As received, the main catalog file contained 3000 records and the
supplemental file 3180 records to blank fill their last blocks.
Records 2971 to 3000 and 3177 to 3180 were deleted, respectively,
to remove the blank records. The logical record length of each
file was 140 bytes, with bytes 1 and 134 to 140 always blank.
These bytes were removed to create the 132-byte/record files, an
advantage for printing one line per source on a standard line
printer.
* 22-Jul-1993: Modifications made at CDS (F. Ochsenbein):
File main.dat: record 126 (AFGL 153): shifted values corrected
records 1752 and 2413, values of GLON transformed from 360 to 0.
* 25-Sep-1995: Description added in readme (Gail L. Schneider, SSDOO/ADC)
* 26-Mar-1999: ReadMe standardized (F. Ochsenbein, CDS), and the
origins of magnitudes were assigned dedicated columns.
