VITAL STATISTICS OF A TRANSIT SEARCH PROGRAMME
==================================================================
Programme:      PISCES - Planets in Stellar Clusters Extensive Search
URL:            http://cfa-www.harvard.edu/~bmochejska/PISCES/
Institution(s): Harvard-Smithsonian CfA
Leader(s):      Barbara Mochejska, Dimitar Sasselov
Collaborators:	Kris Stanek, Andy Szentgyorgyi
Contact: 	Barbara Mochejska  <bmochejs@cfa.harvard.edu>

Aperture:       1.2 m
Focal Ratio:    F/7.7 (? taken from http://linmax.sao.arizona.edu/help/FLWO/48/optics.html)
Focal Length:   9.39 m (? " )
Field of view:  22x22 arcminutes

Number of CCDs: 4
CCD type:       Loral
pixel format:   2048 x 2048
pixel size:     0.333 arcsec

Site:           F. L. Whipple Observatory
Field(s):       NGC 6791

Status and Plans:

Nights of data acquired in 2002:	    52
Nights of 2002 data analysed:		    52 reduced; analysis ongoing.
Planetary transit candidates thereby found: 0
Nights of data hoped for in 2003:	    57 obtained, applying for 21.

Our plans are to observe ~3 open clusters, for ~30 nights per cluster.
Thus far we have been granted 20 nights for NGC 6791 (10 in May, 10 in
June).

In the next stage of the project we plan to obtain better lightcurves
for transit candidates with a 2m class telescope. We also plan to take
spectra with the MMT. A precision of 1 km/s will enable us to identify
and reject stars with companions above 0.0075 M_solar.
