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)

Note on Names: If a galaxy has more than one name, both are included separated by an "=" sign (e.g., I1613=DDO008). Up to three galaxies 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.
