[vsnet-chat 5843] Re: ResSkySurvey and PIXY

Dear Sebastian and Taichi,

I'm really depressed how many possible bad observations
found Sebastian. First a few words.

Sebastain remeber that reference catalog are not TYCHO but
GSC-ACT. I know that it is not the best source for photometric
survey and I'll fix it to TYCHO as soon as possible.

The most problem for now is:
-make script which can deselect stars from image
edges. That's is the reason why some of your variables
have a strange 'eclipse' values. I can't correct it
manually. Simple to many plates and stars.

-maybe flats are not the best. Can anyone tell me how,
step by step, make good twilight flats. Which one will
be better twiligt flats or light box flats?

I must also review why survey produce many good
photometry (see some red Hipparcos variables) and
fail in some fields.

As I see only Sebastian check my observations very
carefully. Maybe I can send (don't worry only GCVS)
observations to him for checking :) Simple I cannot
check these values due not much time!

Sorry for problems

Best regards,
Maciej
