-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
  
- > makewiki.pl exper.skd+One way to check some of this is (as vlbi on ATNF unix machines):
