Description:
This catalog contains the original parallax values used in deriving the
adjusted trigonometric parallaxes contained in the General Catalog of
Trigonometric Stellar Parallaxes (Jenkins, 1963, ADC Catalog Number 1081).
That main catalog contains both the original compilation from 1952 and the
1963 supplement. This catalog contains the original values used for both
1952 and 1963 compilations. Please note that Catalog 1081 has been superseded
by Catalog Number 1174.
The table consists of the star identification numbers (as per Jenkins, 1963),
the relative parallax values for that star and their sources, and the weights
given to those values in averaging them for the main catalog, Jenkins (1963).
Both the main catalog and this catalog contain stars supplemental to the
original 1952 compilation. To add stars such that their serial star
identification numbers remained in order of ascending Right Ascension, the
original integral numbers were changed to ones with one decimal place. Thus,
stars on the original list would have a ".0" added to their identifier
(e.g., star 4 becomes star 4.0). The two stars from the supplemental list
with R.A. between those of stars 152 and 153 (or 152.0 and 153.0) are
identified as 152.1 and 152.2. PLEASE NOTE that in the computer-readable
version, the decimal point has been omitted.
The weights were formed from the corrected probable errors. The reader
should review the source reference for a detailed explanation of the
method by which those errors were assigned. The observatory source codes
are explained in the Notes section of this document.
The source reference also contains numerous notes that are not part of the
computer-readable version. Most of these notes contain star designations, or
attributions for the stellar spectral types that appear in Jenkins (1963).
