Remarks

1 Otero, Sebastian Alberto Symbiotic X-ray pulsar. Mass of the giant donor seems to be above of the 1 solar mass limit for the LMXB class. UCAC3 mags (f= 15.21, a= 14.60) are very bright and may indicate a symbiotic outburst.
2 GCVS Team X-ray pulsar. The pulse period is decreasing: 135s (1971), 112.076s (1979), 109.668s (1980) [M.J.Ricketts, R.Hall, C.G.Page, Ch.H.Whitford, K.A.Pounds, MN 201, 759, 1982.]. The spin-period may be twice longer.
