STF 202 alp Psc = Alrescha. Both components are listed as Alpha CVn variables
of small amplitude, and both may have variable RV. Sca1983f
See Baize & Petit catalog of doubles with variable component. Baz1989d
Absolute quadrant for 1998.657 determined by triple-correlation
techniques Pru2002b
Chevalier identified this star as alp Psc, but gave an incorrect Che1911
declination, leading to its initial designation as 02020+0320 CHE 32. Hrt2012b
PWL 1 AC: SHY 132. Bayesian analysis by Shaya & Olling (2011) indicates very Shy2011
high (near 100%) probability pair is physical.
