MOPS has reported some peculiar magnitudes in y-band MD data offsets and larger scatter compared to predictions of asteroid y-band magnitudes while the same comparison to 3PI photometry looks reasonable (both cases are photometry from the respective diffims). Also, have found photometry from Warp-Stack (WS) difference images for two sequential MD exposures unrealistically different by >0.5 mag.

== Example: MD10 sequential exposure pair, asteroid (12891) (Peter Vereš) ==

Chip/camera photometry from the SMF catalogs below agree to that expected  -- yes,  but can't be more exact because asteroid (12891) previously unstudied.

o6157g0218o: 17.06
o6157g0219o: 17.048





== Example: MD09, TNO145452 (Alan Fitzsimmons) == 

TNO 145452
 * a bit faint but its' the best one I've found so far, as it stays in the field for a long long time. 
 * in MD09 where we can predict the y magnitude should be within 0.1 mag of ~19.3 for the below observations
 * a bunch of y-band exposures and positions on two separate dates:
