-  *  Scans not too short
+  *  First hour reserved for fringe finding
-  *  Scans aligned with 10sec boundary (for ATCA)
+    * Fringe finders listed
-  *  Not too many sources set at any time (elevation)

+  *  Phase reference cycle not too long
+  *  Sources not set at too many stations at any time (elevation)
   *  Slew times not too long (very long or longer than scan)
-  *  Fringe finders listed
+  *  Source positions given to sufficient accuracy
-One way to check all of this is (as vlbi on ATNF unix machines):
+For ATCA
- > vexsum.pl exper.skd
+  * Scans not too short (ATCA loses 15 sec on scan change).
+  * Scans aligned with 5sec boundary (for ATCA)
+  * Encourage 1934-638 for flux calibration
+  * Check frequency of AUTOPHASE_DETERMINE scans
+  * AUTOPHASE_DETERMINE scans must have at least 1 min on 200 mJy source
+  * Do not AUTOPHASE_DETERMINE during the fringe finder section
