1 S. K. Vsekhsvyatskii, 1964. "Physical Characteristics of Comets",
trans. Israel Program for Scientific Translations, NASA TT F-80 /
OTS 62-11031.
The original publication ran approximately 600 pages and included
a table titled "Catalogue of Absolute Magnitudes" which comprises
the data in this data set; plus a second, far more extensive
table called "Observations and Physical Characteristics". The
second table was not included in the English translation used to
prepare these files. There are no head diameters or tail lengths
listed in the Absolute Magnitude table; thus no record from
this reference is included in the "pccds.tab" file.
The description of the table values in this reference indicates that
the quality of the H10 values is given on the following scale:
1 possible error of up to 1 magnitude
2 error does not exceed 0.4 - 0.6 magnitudes
3 error within 0.1 - 0.2 magnitudes

Soviet Astronomy - AJ [in English], Vol. 6, 849-853.
This article continues the compilation begun in the 1964 book.
Updated parameters are included for those comets from the first
publication which were further observed, in addition to the new
comets listed. Head diameters and tail lengths are included in
this and all subsequent publications. H10 quality codes and tail
visibility indicators are also included in this article.

Observed During 1961-1965", Soviet Astronomy - AJ [in English],
Vol. 10, 1034-41.
H10 quality codes are included, but from this point forward none
of the publications include the tail visibility flags. Included
in the article are notes concerning the individual observations
and objects.
The description of the table values in this reference indicates that
the quality of the H10 values is given on the following scale:
1 possible error of order 1 magnitude
2 error does not exceed 0.3 - 0.4 magnitudes
3 error is less than 0.1 magnitudes

This article was completely superceded by the next publication. There
were no comets listed here which were not also listed in the 1974
reference. Since the present data set was compiled only from the latest
available data for each object, there are no records originating from
the table in this article. It is included here for completeness, and
because it is the last of the series available in an English translation.
(The notes regarding objects and observations found in most of the other
articles are not present here.)

Kharakteristiki Komet, 1965-1970gg" [in Russian] (Moskva:
Izdatel'stva Nauka).
Neither H10 quality codes nor tail visibility indicators are
included in this publication, nor are tail type indicators.
There are extensive notes included on the various observations
contributing to the collection.
6 S. K. Vsekhsvyatskii, 1979. "Fizicheskie Kharakteristiki Komet
1971-1975gg" [in Russian] (Kiev: Naukova Dumka).
This publication includes neither H10 quality codes or tail
visibility indicators, but it does include the tail type flags
which have been incorporated into the "pccds.tab" file. Also
included are extensive notes about the individual observations.
