Hi Simon,
Good to chat with you last week. As we discussed, adding the following three quantities that are currently being calculated would satisfy the first interest for my variability studies. More sophisticated moments, etc. can wait for further development.
1. sigma-clipped mean (5-sigma ?)
2. RMS from sigma-clipped mean
3. chisq from sigma-clipped mean
What's the status of this re-calculation and reloading of the database?
Can you remind me the number of sigma for clipping?
Thanks,
Michael
