II/77 Non-Solar X-Ray Measurements (Arens+ 1975)
================================================================================
The Catalog of Non-Solar X-Ray Measurements
Arens J., Rothschild R.
<NASA/GSFC Doc. X-661-75-230 (1975)>
================================================================================
ADC_Keywords: X-ray sources
Description:
The catalog is a compilation of nearly all non-solar X-ray
observations in the 0.1-500 keV range, reported by various
observers. The catalog includes observer's institution, position
in equatorial and galactic coordinates, source names, energy
ranges of observations in keV, energy resolution in keV, temporal
resolution, dates of observations, lengths of observations, types of
detectors, vehicles carrying payload, references, comments of
contributors, and background-type sources. As this catalog was
published in September 1975, it is probably complete through 1974.

Note on equ_coord:
Default source of equatorial coordinates is the UHURU satellite positions.
Other position sources are as follows:
(GC) General Catalogue of 33342 Stars for 1950., B. Boss
(L) Detector entrance slit was perpendicular to the galactic plane
and hence no resolution in galactic latitude
(M) Messler Catalogue
(PSR) D.O. Backer (private communication)
(SNR) Ilovaisky and Lequenx SNR catalogue
(3C) 3C Catalogue Revised
(X) Position given by experimenter or in reference cited.
Remarks and Modifications:
The Catalog of Non-Solar X-Ray Measurements (Arens, J. and Rothschild,
R. 1975 NASA/GSFC X-661-75-230) was received from Dr. R. Rothschild
(NASA/GSFC Code 660) in October 1976. The version received had card
image records with information on each entry. These card images were
80-byte records (the magnetic tape received had a blocksize of 16000
bytes) and totaled 2699 records (1301 entries). Each entry had a
variable number of data cards associated with it (ranging from one to
four), typically with 2 cards per entry where 12 entries had 4 cards.
The input data segments of these card images were separated by a dollar
sign ("$"). The published version of the catalogue (cf. reference
above) did not define the number of entries in it, but a hand count
results in 978 entries and the latest observation date appears to have
been January 1975. Thus, the version presented here contains additional
data (approximately 323 additional records and data at least as late as
January 1976). The last record on the magnetic tape as received from Dr.
R. Rothschild was a dummy 80 byte record with the value of 9999 as the
counter to signal the end of the data set. This record has been dropped
from the present version. A major deconvolution program (the major part
of which was written by Mrs..Susan Ball) was written so as to assign the
observational data into specific bytes so that the user can access the
data in an efficient manner. The previous program (Code 660) used to
process this data required reading all of the data into array areas in
the program - so that as the data base grew, the program grew without
bound. The new defined format presented here permits unlimited data and
a small size program if the user chooses to list it in the same manner
as the published catalogue. There were three types of coordinate data
groups in the original data
1) entries having galactic coordinates
2) entries havinq equatorial coordinates
3) entries with no celestial coordinates, background
For type one above, the equatorial coordinates at epoch 1950.0 were
computed and added to the entry. For type two above, the galactic
coordinates were computed and added to the entry. The background data
entries are at the end of the data base since the tape is primary sorted
by galactic coordinates with a secondary sort by catalogue list number.
