DS24 preliminary analysis updated

[Andrew Bennett <andrew.bennett@ns.sympatico.ca>]

I have today modified the preliminary version of my
analysis of Data Set 24 at
http://www3.ns.sympatico.ca/andrew.bennett/tass/mkivphot/mkivphot.html

I now suggest routine use of light box flats instead
of sky flats as a way of avoiding problems with
sky light gradients. I tentatively propose a survey
strategy.
