+
+  Adding extended sources:
+
+  * create a libautocode extended source table description (DONE)
+  * load the extended source measurements:
+    this could be done within LoadStars or as a separate pass over the file, loading the extended source tables
+    * we can call this function only optionally
+    * need to make the association between the psf and ext measurements via det ID
+  * in find_matches, we could/should record the reference from Stars to the matched average entry
+    that would let us use the PSF position to get the average object match:
+
+  * find_matches_extended
+    * loop over extended sources
+    * use ID to find the corresponding Stars entry
+    * use the averef to find the corresponding Average entry
+    * update the extended source table
+
+  * Write out ext sources with the rest of the data
+
+  where do we put the table? require split?
+
+  (160 byte per detection; PS1 will have 5e8 => 400 GB)
