+== repeating this experiment for other bands (same location) == 
+
+Initially, I did the histogram plots as above, for the same skycell. This was not interesting: Only g band had lots of extra detections. I went hunting around in r band until I found a skycell in lots of cells, and checked that there were lots of extra detections in the other bands (for the same skycell).  Except for y, all the bands had the same chip/orientation for the skycell.  For g,r,i,z, it suggests that the false detections often lie on the same cells on a chip (XY27).  If you look (from the top right) down, the rows are:
+
+ * XY37: row 6
+ * XY37: row 7
+
+ * XY27: row 0 (pattern.row = on)
+ * XY27: row 1 (pattern.row = on)
+ * XY27: row 2 (pattern.row = on) 
+ * XY27: row 3 (pattern.row = on)
+ * XY27: row 4 
+ * XY27: row 5 
+ * XY27: row 6
+ * XY27: row 7 (pattern.row = on)
+
+I can't find a pattern between where there are false detections and whether pattern.row was run or not.
+
+I will make histogram plots (similar to above) tomorrow.
