 You can see the hole at 0,0 -- that should be 0 but instead is something like a million or less entries have that. 
 
-* can I categorize this better, can I find where there are more of these funky batches?
+ * can I categorize this better, can I find where there are more of these funky batches?
   * yes : can I do a query of select batchid, count_big(*) from ObjectThin where nstackdetections = 0 and ndetections = 0 group by batchid --> into query called 'funkybatches'
+  * Basically, every batch has this problem, but it's not too bad, in the sense that 50% have 40 or fewer funky stack/detect = 0 entries, and 90% have 100 or fewer funky stack/detect = 0 entries.
 
+I made a plot of the funky ones.  
 
+The legend is tricky, the bins are divided this way:
+
+ * red = 0 to 0.17% are bad
+ * orange = 0.17% - 0.33% are bad
+ * yellow = 0.33% - 0.50% are bad
+ * green = 0.50% - 0.67% are bad 
+ * blue = 0.67% - 0.83% are bad
+ * violet = 0.83% - 100% are bad
+ * not sure about the white holes (?? I suspect those are the 'violet' ones in python..)

+But basically, problems are scattered throughout, but it's small numbers.
