Note (2): the magnitude values are empty, or consist of either + a digit (from 0 to 7) in position 1, + a digit in position 1 and the letter f (for "fere") in position 5, + a digit in position 1 and the letter i (for "imo major") in position 5, + digits (from 1 to 7) in positions 1 and 3, + digits in positions 1 and 3 and the letter i (for "imo") in position 5, + digits in positions 1, 3 and 5 (1 case only, P Cygni), + or the mention NE for nebulous. Positions 2 and 4 may contain a dot, reflecting the presence of a dot in the original. The file notes.dat provides more details about the significance of these values and the stars to which they apply. -------------------------------------------------------------------------------- Byte-by-byte Description of file: hevelius_h.dat hevelius_b.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 4 I4 --- HNo Hevelius record number 6- 8 A3 --- HCon Hevelius constellation abbreviation 10- 11 I2 --- HNum Hevelius number in constellation 13- 16 I4 --- BHNo ?Record number in this version (1) 18- 20 A3 --- BHCon ?Constellation abbreviation in this version (1) 22- 23 I2 --- BHNum ?Number in constellation in this version (1) 24 A1 --- BFlag [*]?

Only Cam, Cnc, CMa, CMi, CVn are affected. Note (2): a '*' here means that there is a note about this star at the end of the catalog. Note (3): Baily's version doesn't include Tycho numbers. Note (4): Baily represents the special magnitude values (imo, fere, etc.) using fractions (1/4, 1/2, 3/4). The integer part is represented by a digit from 0 to 7 in the first position. The fraction, if any, is represented by its numerator in position 2 and denominator in position 3 (for instance, '412' represents 4 1/2). The magnitude can also be 'NE' for nebulous objects, 'VA' for the nova 593 Cyg 2, or absent entirely. The exact mapping from Hevelius's to Baily's magnitude values is described in notes.dat. -------------------------------------------------------------------------------- Byte-by-byte Description of file: hevelius_z.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 4 I4 --- HNo Hevelius record number 6- 8 A3 --- HCon Hevelius constellation abbreviation 10- 11 I2 --- HNum Hevelius number in constellation 13- 16 I4 --- FHNo Record number in this version 18- 20 A3 --- FHCon Constellation abbreviation in this version 22- 23 I2 --- FHNum Number in constellation in this version 24 A1 --- FFlag [:]?

A single ':' in this field indicates that there is at least one such '::' in this record (there are only 4 instances of this). Note (2): magnitudes from Flamsteed's version are represented by a digit d from 1 to 7 in the first position and an optional digit (d-1 or d+1 except in the case of the Cygnus nova) in position 3. The magnitude can also be NE for nebulous objects or absent entirely. -------------------------------------------------------------------------------- Byte-by-byte Description of file: cross_b.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 4 I4 --- HNo Hevelius record number 6- 8 A3 --- HCon Hevelius constellation abbreviation 10- 11 I2 --- HNum Hevelius number in constellation 13- 16 I4 --- BHNo ?Record number in this version (1) 18- 20 A3 --- BHCon ?Constellation abbreviation in this version (1) 22- 23 I2 --- BHNum ?Number in constellation in this version (1) 24 A1 --- NoId [*+]?

Only Cam, Cnc, CMa, CMi, CVn are affected. Note (2): a '*' here indicates that this catalog entry has no identification; a '+' indicates that the identification is not given directly in the source catalog but has been extracted from the notes (and may be uncertain). Note (3): in the notes, Baily sometimes refers to Lalande's "Histoire Céleste Française" by the observed right ascension and the page number. -------------------------------------------------------------------------------- Byte-by-byte Description of file: cross_z.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 4 I4 --- HNo Hevelius record number 6- 8 A3 --- HCon Hevelius constellation abbreviation 10- 11 I2 --- HNum Hevelius number in constellation 13- 16 I4 --- FHNo Record number in this version 18- 20 A3 --- FHCon Constellation abbreviation in this version 22- 23 I2 --- FHNum Number in constellation in this version 24 A1 --- NoId [*]?
