Notes: 1. Stars #1 and #2 are saturated, and their magnitudes and colours are approximate. They should be used with discretion until accurate magnitudes become available. 2. There is an AAVSO 'e' chart dated 5/1993 with Pv magnitudes. In general these Pv magnitudes are about 0.4 magnitudes too bright. Only stars with an ID number are part of this new sequence.
