The MOST instrument is optimised to perform high precision
photometry in the Continous Viewing Zone (CVZ). In order for a
star to ever enter the MOST CVZ its declination has to fall in
the range from -19º to +36º. The period in a given year when a
star is in the CVZ depends in first order on its right
ascension. As a reference, a star with a right ascension of ~ 6h
40m and a declination of +9º will be at the center of the CVZ on
January 1st each year. The maximum dwell time for a star in the
MOST CVZ is 58 days (8.2 weeks). The MOST spacecraft faces an
annual 'eclipse season' where the satellite is in the Earth's
shadow for up to twelve minutes every orbit and hence is subject
to large thermal changes. This phase starts around May 19th and
lasts until about July 24th of each year. During this period it
is expected that MOST's photometric quality will deteriorate
slightly from its nominal specification. Objects with a right
ascension in the range of 16-18h are affected. During this
period science programs will
