Yeah, I'm just talking about the no-brainer stuff. I don't discard any 
observations.

1. Correct field.
2. Correct variable star.
3. Current chart or sequence.
4. Properly dark subtracted and flat-fielded images.
5. 2 to 5 comp stars that agree.
6. Reasonable aperture sizes.
7. Correct entry of comp star magnitudes.
8. Correct time. I set my PC clock to the atomic clocks every night 
before I go out and write UTC to my FITS headers automatically. I 
usually double-check computed JD on the USNO site.
9. Accurate reporting of the variable name, dates and magnitudes.
