+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) ==

+ * y-band magnitudes you get from the SMF catalogs is much more in line with what we would expect. We can't be more exact because previously unstudied.
+
+
+== 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:
