I/195 FOCAT-S Catalogue (Bystrov+ 1994)

FOCAT-S: Pulkovo photographic Catalogue of Southern Hemisphere

Description:
This is a new reduction of FOCAT-S photographic catalogue of
southern stars. This reduction has to replace the preceding one.
The differences from previous version are as follows:
1. The new version was sorted according right ascension of stars inside
10-degree declination zone;
2. New proper motions were calculated for all almost stars. New
Astrographic Catalogue plate reduction was developed for this aim.
The average rms of new FOCAT-S proper motions is 0.002 - 0.003 "/year;
3. The number of the Astrographic Catalogue star positions used for the
proper motion calculation is added;
4. The magnitude (mag) and spectral type (Sp) columns were revised
significantly: some errors were corrected; stars identified
in C.S.I. catalogue have got Mag, Sp from this catalogue as it was
in previous version. Other stars have got Mag, Sp from PPM-S
catalogue.
5. The list of Durchmusterung star numbers was changed. Now it contains the
Cape Photographic Durchmusterung (CPD) numbers for stars in [-90, -23]
declination zones; Cordoba Durchmusterung (CoD) star numbers are used
only if it was impossible to identify star in BD or CPD. Format of
this column was changed also.
6. PPM catalogue star numbers were added.

Note (1): the flag has the possible values:
" " : final proper motions, derived by the new Astrographic
Catalogue plate reduction;
"C" : preliminary proper motions, derived using CPC2 catalogue
"P" : proper motions are taken from PPM catalogue
"S" : proper motions are taken from SAO catalogue
"*" : proper motions are unknown.
Note (2): The flags on magnitude and spectral type indicate:
" " : Mag, Sp are taken from C.S.I. catalogue
"P" : Mag, Sp are taken from PPM catalogue
"F" : Mag, Sp are taken from FOCAT-S source list.
Note (3): The Durchmusterung designation is made of
=> Durchmusterung zone and star number (A8)
=> Durchmusterung star component (A1)
=> Durchmusterung designation (A1), as:
"B" : Bonner Durchmusterung star number
"P" - Cape Photographic Durchmusterung star number
"C" - Cordoba Durchmusterung star number.
