A2390: galfacts commensal survey with Igalfa

---

Intro:

01may08: high cals not firing correctly..

• Top:  1800 seconds of total power vs time:
• The  dashed red line is the first turn around, the dashed green line is the second turn around.
• 2nd: blowup of the first second of data taking. The high cal is winking at 25 hz for about .25 seconds.
• 3rd: start of first turn around.
• there is a dropout and 681.5 seconds (dashed blue line).
  
• the high cal winks for about  .5 seconds and there are no cals.
• 4th:  the entire first turn around period.
• from the dropout to the restart of the winking cal is about 13 seconds.

Conclusions:

• The high cal is not on solid for 3 seconds at the turn around
• Cause: the calport 3 command was not sent to select the wapp input at the cal multiplexer.
• The high cal winks for about .3 seconds
• the program is switching from low cal to high cal before turning of the winking cal.
