+* trying to make sense of mosaic.Mcal vs image.Mcal in the context of UBERCAL:
+
+  * relphot_images:
+    * load_images (convert raw FITS table to Image structure, select subset matching selection)
+      * initMosaics (associate mosaics to images (gpc1 photcodes only))
+      	* initMosaicGrid (define spatial range of mosaics [only used by grid analysis]; set Mcal to <image.Mcal> and image.Mcal to 0.0)
+    --- calculate image or mosaic Mcal values
+    * setMcalFinal (set image.Mcal = mosaicMcal)
+
+  * relphot_parallel_regions:
+    * assign_images
+      * makeMosaics (equivalent to initMosaics, but works on full image table, not subset)
+      * setMosaicCenters (set Mcal to <image.Mcal> and image.Mcal to 0.0) <--- this is wrong!
+      (sends images ONLY, not mosaics, to remote machines)
+      (slurps back new image values, applies to db)
+      
+  * relphot_parallel_images:
+    * makeMosaics (associate mosaics to images, gpc1 photcodes only)
+      * initMosaicGrid (needed in this one)

 For 'mosaic' zero points, I define the mosaics by grouping the images
