[vsnet-campaign 592] RZ Leo: one more attention

[Taichi Kato <tkato>]

   I should have reminded one more thing.  In order to obtain good
time-series photometry, please keep your PC's clock adjusted at least
to 1 sec (or hopefully less than this).  Please ensure excat exposure
times are recorded in your images (please confirm whether the recorded
times represent the start, mid or end exposure; if this is not certain,
one may better independently record start exposure times manually).
When you report the results, reduce these times to mid-exposure times.

   If your CCD is equipped with on-chip binning, choose the binning
so that 1 pixel corresponds to ~2 arcsec (even larger pixel size is allowed
depending on the actual seeing size).  Since the field is not crowded,
high spatial resolution is not necessary.

Regards,
Taichi Kato
