Note (2): a '*' here indicates that this catalog entry has no identification; a '?' indicates a possible but less secure identification; a '+' indicates that the identification has been corrected from an obvious error in the catalog or inferred from catalog notes or non-standard designations. Note (3): a '*' here indicates that the indexless Bayer letter has been interpreted as this component. Note (4): component letter(s) from the Hipparcos catalog (or sometimes the SAO or Bright Star catalog). Note (5): magnitude from the Hipparcos catalog or the SAO catalog. -------------------------------------------------------------------------------- Byte-by-byte Description of file: dists_mo.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 4 I4 --- MNo ?Record number in the manuscript catalog 6- 9 I4 --- TNo ?Record number in Progymnasmata catalog 11- 14 I4 --- KNo ?Record number in Tabulae Rudolphinae 16- 18 A3 --- TCon Constellation abbreviation 20- 21 I2 --- TNum ?Number in constellation 23- 29 F7.2 arcmin dLO ?Difference in longitude.cos(LA) (1) 31- 37 F7.2 arcmin dLA ?Difference in latitude (1) 39- 44 F6.2 arcmin dist ?Distance between match and Tycho (1) -------------------------------------------------------------------------------- Note (1): difference (HIP - Tycho), or (SAO - Tycho) if there is no HIP match, based on the positions in tycho_m.dat and identifications in ident_o.dat -------------------------------------------------------------------------------- Byte-by-byte Description of file: tycpto_oo.dat -------------------------------------------------------------------------------- Bytes Format Units Label Explanations -------------------------------------------------------------------------------- 1- 4 I4 --- MNo ?Record number in the manuscript catalog (G1) 6- 9 I4 --- TNo ?Record number in Progymnasmata catalog (G1) 11- 14 I4 --- KNo ?Record number in Tabulae Rudolphinae (G1) 16- 18 A3 --- TCon ?Constellation abbreviation (G1) 20- 21 I2 --- TNum ?Number in constellation (G1) 23 A1 --- Status [=x*] status (G2) 25- 28 I4 --- PNo [1/1028]?

Note (G2): status of this Tycho Brahe object with respect to the other catalog, according to the identifications retained in the file ident_o.dat for Tycho's catalog and either ident_o.dat or ident.dat for the other catalog: = indicates that the Tycho and other catalog entries are identified as the same object or collection of objects, > indicates that the Tycho catalog entry includes the other catalog's entry, and more (for instance if two components of a double star are distinguished in the other catalog but lumped into one entry in Tycho's catalog), x indicates that the Tycho catalog entry has an identification, but no match in the other catalog, * indicates that the Tycho catalog entry is unidentified. -------------------------------------------------------------------------------- History: * 2022-04-10: new revised version. ================================================================================
