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

Future of Astrometry QC
● verify()– enforce limits
● inspect()– pairs plots
● compare()– correlate residuals over time
● Documentation– How-To– better error reports
