Revision as of 08:14, 9 July 2011

problems to solve: 

* NOSTAR in header
* ople server communication for mirc spooler does not seem to be working at all.
* remove extra digits in fiber explorer.
*

UT2011Jul09

Starting up on sky for the run.

all times are local.

20:30p on sky. Our first star is a calibrator for delta sco, HD 133670. we found some of the fiber images to be crap -- esp. #4 (W2) We went to brighter star DEL SCO to try to optimize fiber focus.

r0~3-4cm

we are re-focusing beam4 (W2) which is really bad!! this means the actual telescope is out of focus.

22:27p we have had hard time optimizing flux. the r0 is crap and highly variable and we are observing at low elevation (30 degrees). we finally decided to focus on this more seriously and find a brighter target (hd150450) which is H=0, V=5. for just focusing.

we are doing a super systematic focus work... wait and see! {Focus Test}

1:00am. Now that we have "good" focus, we are now changing POPs to the setting for Zet And. Then we will try to find fringes on a calibrator and test the Group delay tracker (GDT). Stefan/Fabien have been fixing the gdt2 delayline controller!

1:13am. 4 POPs changed!!
