Verification Parameters

● Minimum and maximum NREF● RMS of residuals

– RMS not currently stored in DB– can be estimated from SIG_DRA and SIG_DDEC

● Max of residuals– limited to 3*RMS

No NREF Restriction

John P. McFarland 20 Apr 2006

20 > NREF > 2000

John P. McFarland 20 Apr 2006

50 > NREF > 1500

Documentation

● How-To– What is bad astrometry?– How to recover from bad astrometry?– Checklist

Future of Astrometry QC

● verify()– enforce limits

● inspect()– pairs plots

● compare()– correlate residuals over time

● Documentation– How-To– better error reports
