+
+  relastro currently loads the set of detections, averages, and image,
+  and sets up arrays of pointers to define the relationships beteen
+  the detections, objects, and images.  This is probably an acceptable
+  scheme.  
+
+  However, the generation of those index arrays is probably very
+  inefficient.  Currently it is written for the old DVO tables in
+  which there was no real link between the detection and image.  We
+  are trying to move to a situation where each detection has a
+  reference to the image (imageID).  If this is unique, then we should
+  be able to make these links directly.
+
+  Outstanding issues:
+
+  * am I getting the correct set of matches for the mosaic images? 
+    ie, do getImageRaw & getImageRef return the correct list when the
+    image is a DIS mosaic image?
+
+  * is the operation in fit_apply_coords doing the correct thing?
+    compare this to psastro code.  This should not be a problem since
+    we are only fitting in the linear frames.  we are just fitting
+    simple polynomials.  We are not changing the reference coordinate
+    for the projection.
+
+  * measure the errors?
+
+  * apply the magnitude errors as weight?
+
+  * improve matching process with the index information available?
+
+  * add the ability to down-weight groups of detections by photcode?
