Description:
    (adapted from the "Documentation for the Machine-Readable Version
     of the Detailed bibliography of the surface photometry of galaxies
     by Lee E. Brotzman and Robert S. Hill (ADC), SASC-T-1-5810-5006-84,
     July 1984)
    The bibliography supplies coded information about the methods of
    observation and reduction, types of photometric data, limiting surface
    brightness, and the general purpose of each paper for about 650
    galaxies and 300 references.

Note (1):
    The name consists of the catalogue designation immediately followed
    by the catalogue number (except in the case of a commonly used name).
    The catalogue designations are, in order of appearance:
      N                   New General Catalogue (NGC)
      I                   Index Catalogue (IC)
      MK                  Markarian; galaxies with ultraviolet continuum
      DDO                 David Dunlop Observatory dwarf galaxies
      VV                  Vorontsov-Vel'yaminov
      LMC, SMC            the Large and Small Magellanic Clouds
      FORNAXDW, SCULP.DW  the Fornax and Sculptor dwarf galaxies
      A                   anonymous galaxies not appearing in any of the
                            above catalogues. The number follows the rules
                            given in RC2
      U                   Uppsala General Catalogue of Galaxies (UGC)
    The last 15 records of the file list the main galaxy clusters
    which have been studied (excluding Virgo).
Note (2):
    The Number of galaxies may be larger than the number of galaxies with
    documented surface photometry in the paper (e.g., Oemler 1976;
    de Vaucouleurs and Aguero 1973)
Note (3):
    Total number of plate exposures available for the galaxy (sometimes
    several exposures may be made on one plate). This is not always the
    number of reduced plates, as some may be trailed for orientation
    (Ables 1971) or used for visual inspection only.
Note (4): Plate scale of the observations:
    H = high (less than 20 arc seconds per mm);
    M = medium (between 20 and 50);
    L = low (over 50).
    The plate scale is sometimes changed with a focal reducer in works
    with digital detectors.
    An asterisk in byte 27 indicates that the plate scale was not given
    in the paper.
Note (5): Source of data:
    A = analog two-dimensional measurement of photographic plate
        (e.g., Joyce-Loebel, Sabatier effect);
    1 = one-dimensional digital scans of plate or film;
    2 = two-dimensional digital scanning of the plate or counts of
        silver grains;
    G = grid of photoelectric photometry measurements;
    S = photoelectric drift scans;
    D = digital two-dimensional detector (e.g., CCD, IPCS, Vidicon).
    An asterisk in byte 31 indicates that the source of the data was
    not given in the paper.
Note (6):
    Highest and lowest resolution of the photometric maps and profiles, or
    minimum and maximum scanning apertures in seconds of arc. The aperture
    size is defined as the length of a side of a square aperture, the
    geometric mean of the sides of a rectangular aperture, or the diameter
    of a circular aperture. This resolution has nothing to do with the
    atmospheric seeing.
Note (7): Method is defined as follows:
    A = photoelectric aperture photometry;
    B = brightness of the night sky (measured photoelectrically or
        on another plate);
    D = photoelectric drift scans or previously published profiles
        of the galaxy;
    E = extrafocal images of standard stars;
    S = standard stars or other objects;
    * = unspecified;
    U = uncalibrated.
Note (8): Photometric passbands and corresponding limiting surface
    brightness (to the nearest magnitude per square arc second). The bands
    are U, B, V, R, I with an additional column (E) for any narrow
    emission line band (H ALF, OIII, etc.). Photometric observations in
    other systems were forced into the closest band (e.g., J plates are
    listed under the B band). For the few papers which will not fit into
    this classification scheme we simply list the total number of colours
    that were observed (e.g. Swaans 1980, Pronik and collaborators).
    The U, B, V, R, I, and E, bands are given in that order, each one
    occupying 3 bytes.
Note (9): the two-dimensional information includes:
    P = photograph;
    D = isodensity tracing;
    I = calibrated isodensity tracing or iso-intensity map;
    N = numerical intensity or colour index map.
Note (10): the one-dimensional intensity profiles include:
    A = major axis;
    B = minor axis;
    E = equivalent luminosity profile (i.e. surface brightness versus
        equivalent radius r* = sqrt(ab);
    O = other profile: other position angle, azimuthal luminosity profile,
        colour profiles, profile along spiral arm, colour-colour diagrams
        of pixels, position angle of isophotes at different intensity levels,
        etc.
Note (11): This is not intended to be a complete description of the paper,
    but only an indication of some of the main subjects covered.
    1. spatial luminosity distribution;
    2. dust lanes, absorption, scattering laws;
    3. bulge, disk, arms, etc. decomposition;
    4. star formation, stellar populations, metallicity;
    5. individual objects: HII regions, globular clusters;
    6. nucleus, compact objects;
    7. ellipticity of isophotes or isophote twists;
    8. outer halos, filaments, intergalactic connections;
    9. dynamics, rotation, mass/luminosity, mass models;
    A. origin, evolution of galaxies;
    B. tidal interaction;
    C. spectral energy distribution;
    D. extragalactic distance scale.
Note (12): The reference is given as the first author, followed by a "+"
    if there are any coauthors, and the year of publication. If the galaxy
    name in bytes 1-9 is one which appears in another catalogue, a cross
    reference to the primary name is listed in this field
    (e.g. MK190 = N3928)

    may be given in a record, each in a 20-byte field starting at
    byte 21, 41, and 61.

Historical Notes:
  * July 1984 (from ADC)
    The original tape of the SPG catalogue was supplied to the
    Astronomical Data Center (ADC), Goddard Space Flight Center, by the
    Centre Donnees Stellaires (CDS), Strasbourg, France in late 1983. This
    tape contained the main data file and the reference file, which were
    modified at the ADC by deleting blank records, deleting heading
    records that did not conform to the formats detailed above, and
    stripping off the CDS number placed in the first eight bytes of each
    record. The two additional index files, galaxies sorted by reference
    and the index by galaxy, detailed above, were added by the authors of
    this document at the ADC, and were generated by extracting and sorting
    certain fields from the original two files.
  * 13-Jun-1995 (at CDS)
    The bytes used to express the resolution values Hresol and Lresol
    have been expanded from F4.0 to F6.1 to accommodate the large numbers.
