V1.02 (Feb 25 2013) Added adjustable photemetric aperture. Prior to this all S/N estimates were made assuming a photometric aperture equal to the seeing disk. Bug fix: prior to this version the S/N and exposure time estimates were made assuming all the flux fell within the aperture, now a correction is added to account for aperture loss.

V1.01 (Oct-15-2012) Updated zeropoints (mirror cleaning). Added all filter. Included guider on/off suggestions in strategies. Rounded strategies to to either dice 5, square 9 or poisson-11 and higher. Included Vega or AB mag option.

V1.0 Created.
