The designation system of the planetary nebulae of this catalogue follows the recommendations of IAU Commission 5 (Astronomical Nomenclature) with the structure: PN Glll.l+bb.b where PN means "Planetary Nebula", G stands for "Galactic Coordinates", and lll.l+bb.b stand for the galactic longitude and latitude respectively, truncated to one decimal place. The designations following this system appear in the columns labelled "PNG" in the tables described below, where the "PN G" prefix has been stripped. Data concerning the 1143 true and probable planetary nebulae (part II of the publication) have been grouped in a set of related tables described below, all sorted by the "PNG" column. Note that, unlike the printed volume, only the bibliographic references corresponding to data listed in the tables are provided here, in the "refs.txt" file. Copies of the complete catalogue, including the Finding Charts (Part I) can still be ordered at the ESO Information Service, Karl-Schwarzschildstr. 2, D-85748 Garching bei Muenchen, Germany, at a price of DM 135.

Publ. 2, n.5, 63). The object Wray 17-88 was not detected as having any emission line and is this not a PN. Kohoutek in 1983 gives the designation 359+3 4 to the object Al 2-E found by Allen and this should be used, although Allen himself gives 359+3 5. ================================================================================ (End) Francois Ochsenbein [CDS] 21-Dec-1994 SSD-T-1-0338-0097-83 DOCUMENTATION FOR THE MACHINE-READABLE VERSION OF THE STRASBOURG CATALOGUE OF GALACTIC PLANETARY NEBULAE (ACKER, MARCOUT, AND OCHSENBEIN 1980) April, 1983 Contract NAS 5-27393 Robert S.

This document describes a machine-readable version of the Strasbourg Catalog of Galactic Planetary Nebulae (Acker et al., 1981). The original version of the machine-readable dataset was supplied by the Centre de Donnees Stellaires, and has been reformatted as described in Section 4. Most of the information in Section 2 is repeated from Acker et al. (1981), part 1. Also, the following is quoted directly from that paper: The aim of this catalogue is to provide a list of data concerning all known planetary nebulae (PN). The total number is 1455 including 1036 listed in Perek and Kohoutek (PK) catalogue (1967), and including including doubtful cases. The additions come from Sanduleak (1975, 1976), Acker and Marcout (1977), Weinberger (1977), Peterson (1977), Kohoutek (1978), Stephenson (1978), Allen (1979), Murdin et al.

In that case, PK 358 + 3.10 (zero in byte 9) is differentiated from PK 358 + 3.1. 10-26 Equatorial coordinates (1950). These agree with the radio coordinates of Higgs (1971) to within 0.01 minutes of right ascension and 0.1 arcminutes of declination. 10-11 Hours of right ascension I2 12 Blank 1X 13-17 Minutes of right ascension F5.2 18 Blank 1X 19 Sign of declination ("+" or "-") A1 20-21 Degrees of declination I2 22 Blank 1X 23-26 Arcminutes of declination F4.1 27 Blank 1X 28-32 Visual magnitude 28 ">" or blank A1 29-32 Visual magnitude of planetary F4.1 nebula, integrated over its surface.

A reminder to the user is included of the PHYSICAL tape attributes of which knowledge may be required to read a tape copy of the catalog. Table 3-1. File Characteristics Strasbourg Catalogue of Galactic Planetary Nebulae (Acker, Marcout, and Ochsenbein 1981) Catalogue Abbreviation PLN Number of Files 1 Logical Record Length (Bytes) 52 Record Format (IBM OS/JCL) Fixed Total Number of Logical Records 1455 Other attributes of the tape will vary from copy to copy, as their values are discretionary, or else depend on the computer for which the tape was copied. These include the following: Number of Tracks Density (Bits per Inch) Blocksize (Bytes) Blocking Factor (= Number of logical Records per Block*) Total Number of Blocks Character Code The values of these parameters for your tape are supplied separately. You may wish to write them in above. 3-1 SECTION 4 - REMARKS AND MODIFICATIONS The orignal version of this catalogue was received by the Astronomical Data Center (ADC), NASA Goddard Space Flight Center, in July 1982, from the Centre de Donnees Stellaries (CDS). The present version was generated from the CDS version, the purpose of all the modifications being to adapt the file for use with FORTRAN programs. (No data values were altered.) To this end, the following were done: (1) Commas in numbers with decimal fractions were made decimal points to conform with FORTRAN usage. (2) Decimal points were added to integral values of data that will be read with "F" formats according to Table 2-1 above. (3) A very few data appeared to be misaligned within the record, e.g., '7 ' for ' 7'. These data were realigned. (4) The one variable central star (PK 289-0.1) was indicated by "VAR" in the magnitude field. This was changed to a "V" to the right of the magnitude field. (5) The CDS catalogue-number tag at the beginning of each record was removed, since this version is not identical in format to the CDS version. In addition, the catalogue data were checked by a FORTRAN program for valid range, such as right ascension between 0 and 24 hours. No errors were detected by this check.
