This memo is the result of the development of the documentation for the machine-readable version of the catalogue and includes the basic information given in the original preface of the published catalogue. This memo should be distributed along with any copy of the machine-readable version of the catalogue. 1-1 SECTION 2 - FILE CONTENTS A byte-by-byte description of the contents of the catalogue is given in Table 2-1. The information in the "Description" column is derived mainly from the published version of the catalogue whenever possible. The "Suggested Format", column is for FORTRAN-formatted reads. Table 2-1. Fi1e Contents (1 of 7) WACKERLING CATALOGUE OF EMISSION-LINE STARS Suggested Bytes Description Format 1-4 Sequential counter based on the order of the I4 catalogue in increasing right ascension order at epoch 1900.0 (value of 1 to 5326). Of these 5190 sources (97.4%) are within 20 degrees of the galactic equator. 5 Blank 1X 6-14 Star name: Greek letters abbreviated to three 9A1 letter codes (e.g. alpha is coded as ALF); Harvard Revised (HR) numbers; New General Catalogue (NGC) numbers; Index Catalogue (IC) numbers; variable stars designations (e.g. "AX PER" is coded as "*AX PER" and "T LEO" is coded as "**T LEO"); Bayer or Flamsteed names. 15 A colon (":") in this byte indicates uncertain A1 star name (cf. bytes 6-14), otherwise this byte is blank. 16-23 Identification codes: This is usually one of 8A1 the identifications from the individualized catalogue entries (cf. bytes 25-86) but may also be a variable star name (e.g. "AX PER" is coded as "*AX PER" and "T LEO" is coded as **T LEO"); Durchmusterung number may be given without spaces (e.g. "-23 5754" is coded as "-235754") so can look like an HD number with a sign. 24 Blank 1X 25-31 Henry Draper (HD) or Extension Number 25-30 HD number I6 31 Blank, "A", "B", "F" or for A1 uncertain designations this byte is a colon ":". 2-1 Table 2-1.

It was received as a 7-track tape which was converted to a 9-track tape with EBCDIC characters. Other than the character conversions noted elsewhere, all ampersands ("&") were converted to plus ("+") signs with the following exceptions: Published # Star Name R.A.(l900.0) m_B Machine-Readable Bytes: l40-l42 143 hr min ------- --- 1608 CP Pup 8 7.97 17.+V 17 V 4000 Vll48 Sgr 18 2.90 16.+V 16 V 4068 YY Her 18 l0.30 13.+V 13 V 48l0 V407 Cyg 20 58.68 16.+V 16 V The original version was written as two card images of 80 bytes each where the first byte of the first card image was always equal to a one ("1") and the first byte of the second card image (i.e. byte 81) was always equal to a two ("2"). All of these ones and twos have been deleted. The published catalogue has a column ("other") which gives references other than those for which there are specified columns. It was not included in the version that we received from the author and is still not included in this version of the catalogue. The identifier portion of the record has been reformatted as follows: (1) The sequential number (originally immediately followed by a zero which has been deleted) and the ID (identifier, which is the key to the published catalogue) were moved to the beginning of the record. The ID was repeated on both of the initial card images so the second number was deleted from the machine-readable version described herein. The Additional Stars ("A") designation for the Mount Wilson Catalogue and the planetary nebulae ("P") designation for the Henize objects have been each moved to their own byte so as not to interfere with the respective numerical fields for the number portion of the given identifier. The equatorial coordinates have been computed and added in radians at both epochs (l900.0 and l950.0) for convenience. Trigometric functions in Fortran require the arguments in radians. The hardcopy version uses a colon (":") following a catalogue number to denote that the identification of the star with that catalogue object is uncertain. The magnetic tape version which we received used a zero for this purpose, 4-l so we replaced the zero with a colon. The hardcopy left and right square brackets ([ and ]) in the spectral type column appeared as double quote (") and minus sign ("-") respectively. We replaced these symbols with open and close parentheses (cf. bytes 133 and 134 in Table 2-1). We would like to acknowledge the work of Dr. Phil Hodge who did a great deal of the reformatting of this machine-readable version of the catalogue. Reference: L.R.
