v9 v10 44 44 that are not matched with a detection in another band while detections for the other filters must match 2 other bands 45 45 before forced photometry is done. 46 46 [[BR]] 47 47 48 If we plot the ratio of the number of matched detections to the number of detected sources for each band we can see these outliers. 48 49 The following plots shows the ratio for the r band versus that in the ratio in i band for each stack. The plot on the left shows the full range 49 50 including the outliers wile the plot on the right zooms in on the values near zero. 50 51 [[Image(mdr.jpg)]] [[Image(mdrzoom.jpg)]] 52 [[BR]] 51 53 52 54 The plots for g and z show the same shape while the y band plot does not show the tail. … … 56 58 We propose re-running psphotStack for these skycells changing the rule that matched detections are created for all unmatched y band 57 59 detections if some criteria is met. We can get rid of the worst of the outliers with the cut. This effect is seen in 3% of the skycells 58 north of 20 degrees declination 60 north of 20 degrees declination. 61 [[BR]] 62 59 63 {{{ 60 64 Nmatched_i / NDetected_i > 0.4 && Nmatched_r / NDetected_r > 0.6 61 65 }}} 66 [[BR]] 62 67 63 68 [[Image(mdr_cut.jpg)]]
