limiting magnitudes for a detection with ULTRACAM as a function
of exposure time on the WHT.
Solid (red) curves are for ULTRACAM, with the upper
curve representing dark time and the lower curve bright time.
Dotted (green) curves are also for ULTRACAM, but
using on-chip binning. Dashed (yellow) curves are
for a photo-electric photometer.
limiting magnitudes for a detection with ULTRACAM as a function
of exposure time on 2 m (yellow), 4 m
(green)
and 8 m (red) telescopes.
