Spin-folded visual light curve of EX Hya

  Continuation of vsnet-chat 1144:

  I have used the same data, corrected to TD, then to BJD(TD) and folded
using the current ephemeris derived from C. Hellier and L. N. Sproats (1992).

  Max.BJD(TD) = 2450895.29633 + 0.04654606 E  (corresponding to the original
  E = 283590 in Hellier and Sproats).

  The folded light curve rather safely indicates maximum around phase zero.
