97recno 97  Record number assigned by the VizieR team. Should Not be used for identification. (meta.record)

NameAW Sge  variable star name. (meta.id;meta.main)
RA195019 56 20.66 "h:m:s" (i) Right Ascension 1950 (pos.eq.ra;meta.main)
DE1950+16 33 17.3 "d:m:s" (i) Declination 1950 (pos.eq.dec;meta.main)
e_RA1950 0.018 s formal (internal) mean error of the measurements at the plate location of the variable star as derived from the least squares solution to the position of the standard stars in right ascension (multiplied by cos(delta)) in seconds of time. (Note 1)   (stat.error;pos.eq.ra)
e_DE1950 0.29 arcsec formal (internal) mean error in declination in seconds of arc. (Note 1)   (stat.error;pos.eq.dec)
Epoch1951.72 yr epoch of the coordinates. (Note 2)   (time.epoch)
SourcePOSS  the type of the plate on which the positions were measured, or source of the measurements: L = Lopez (1985, IBVS 2837) W = Williams (1983, ApJS 53, 523) K = Kiplinger (1985, IBVS 2488) Other abbreviations are self-explanatory. (meta.note;src.morph.type;instr.plate)
RefCatAGK3  Source catalogue for the reference stars. In most cases the AGK3 or the PPM catalogue could be used. However, for some fields we had to use the SAO catalogue which has a somewhat inferior accuracy. (meta.ref;pos.frame)
Nref 15   Number of reference stars for the coordinate determination (only for our own measurements) (meta.id)
Rem   a code for remarks (Note 3)   (meta.note)
