================================================================================
ADC_Keywords: Rotational velocities
Description:
The catalog contains 1005 main-sequence single stars; 360
spectroscopic and eclipsing binaries; 189 Be and shell stars; 243
peculiar B- and A-type stars, and 1277 supergiants, giants, and
subgiants, for which v sin i has been determined from 1949 to 1970.
Rotational data are essentially in the Slettebak-Kraft system. The
catalog provides visual magnitudes, color indices, galactic
coordinates, spectral classifications, absolute visual magnitudes,
adopted rotational velocities, descriptive information, binary types,
luminosity classes, orbital periods, right ascension and declination
(B1900.0), and cross identifications to the numbering systems of The
Henry Draper Catalogue (HD), the Durchmusterung catalogs, and Aitken
Double Stars Catalogue (ADS).

Remarks and Modifications:
The machine-readable version of the Bernacca and Perinotto Catalogue of
Stellar Rotational Velocities was received from the Centre de Donnees
Stellaires (CDS). The original published version of this catalogue
is in 5 parts:
1. I-- Main sequence single stars
2. II-- Main sequence spectroscopic binaries and eclipsing systems
3. IIIa -- Stars with peculiar spectrum; Be and shell Stars
4. IIIb -- Stars with peculiar spectrum; Bp, Ap, Am, Apec
5. IV-- Evolved Stars
The magnetic tape received from the CDS contained 2856 records but did not
include section IIIb. The new total number of records is 3099. Initially the
logical record length was 84 bytes, however with the added information the
new logical record length is now 152 bytes.
The following is a list of modifications to the CDS tape version of the BPRV
Catalogue which represents the current version.
1. Section IIIb was keypunched and inserted. (Code 5 in byte 5)
2. All BD cross-identifications were keypunched and added.
3. Running counter was corrected.
4. Identification number within each section was added.
5. Equatorial coordinates (1900) were computed from the galactic
coordinates as originally given on the CDS tape.
6. Missing designations that were added:
a. ") " for Aitkens Double Stars .
b. Type of system used in determining visual magnitude.
c. Type of system used in determining luminosity class.
d. 1, 2, ? with SB (Spectroscopic Binary) designation.
e. RV and RV ? (RV VAR) were added to appropriate sections
(II and IIIa).
f. Extra information describing spectral type and luminosity
class was added. (e. g., D for Dwarf).
7. A coded numbering system for luminosity class was added
8. The coordinates (Galactic and Equatorial) seem to be inconsistent.
In a sample check made with coordinates from the HD Catalogue, a few sets of
coordinates were found to be incorrect. We are awaiting a reply from Dr.
Bernacca (Italy) to clear up this problem. Meanwhile, another tape has been
made containing the BPRV records numbers that have HD numbers. This tape
contains correct galactic and equatorial coordinates which were extracted
and calculated, respectively, from the machine-readable version of the Henry
Draper Catalogue. We are prepared to correct the coordinates on the BPRV
tape if this is what is required.
ADC July 1995 conversion of documentation to standard ReadMe. Verification
showed several errors which could not be resolved. In records 965 and 1760
the Ident1 column had a number preceded by the letter "R". The "R" was
removed but the reference is most likely to a different catalog. In record
2120 the HD number was found to be unreadable. The field only contained
the value " 1 " and was modified to " 1" to comply with the format
but is most likely wrong. The values for the uncertainty in the rotational
velocity u_Rot_Vel in records 2489, 2574, and 2615 were not aligned "7 " was
changed to " 7".
