Description:
Astron was a Soviet spacecraft launched on 23 March 1983, and it was
operational for eight years as the largest ultraviolet space telescope
during its lifetime. Astron's payload consisted of an 80 cm
ultraviolet telescope Spica and an X-ray spectroscope. We present 159
low resolution spectra of stars obtained during the Astron space
mission (Tables 4, 5; hereafter table numbers in Boyarchuk et al. 1994
are given).
Table 4 (observational log, logs.dat) contains data on 142 sessions
for 90 stars (sorted in ascending order of RA), where SED was obtained
by scanning method, and then data on 17 sessions for 15 stars (also
sorted in ascending order of RA), where multicolor photometry was
done. Kilpio et al. (2016, Baltic Astronomy 25, 23) presented results
of the comparison of Astron data to the modern UV stellar data,
discussed Astron precision and accuracy, and made some conclusions on
potential application areas of these data.
Also 34 sessions of observations of 27 stellar systems (galaxies and
globular clusters) are presented. Observational log was published in
Table 10 and data were published in Table 11, respectively. Also 16
sessions of observations of 12 nebulae (Table 12 for observational log
and Table 13 for data themselves) are presented. Background radiation
intensity data (Table 14) are presented in Table 15. At last, data on
comets are presented in different forms. We draw your attention that
observational data for stars, stellar systems, nebulae and comets are
expressed in log [erg/s/cm^2/A], while for comets data 10E-13
erg/s/cm^2/A units are used, hydroxyl band photometric data for
comets are expressed in log [erg/s/cm^2], and for the background data
it is radiation intensity expressed in log [erg/s/cm^2/A/sr].
