Re: Error was GSC 748-1618 period

I may have misinterpreted Michael K., since there are conventions
for light curves that he may not be following.  In the table
below, does "Min" correspond to the (V-I) value at the V-band light
curve minimum, and "Max" correspond to the (V-I) value at
the V-band light curve maximum?  Or are they just the minimum
and maximum values of (V-I) in the dataset, with no correspondence
to the light curve?  The former is the normal convention.
