Statistics - so far
Basic results are set out in Tables 1, 2 and 3. The search commenced with four nights at the end of 1994. During 1995 a total of 52 nights were allocated. So far, during 1996 (up to May 9), a total of 25 nights have been allocated to this project. This included a record night when 376 galaxies were observed in just over eight hours. The number of different galaxies included in all of this observing is not known, but is probably around 2000.
