LDG Commissioning: Performance Verification - 26 April 2010 UT

Night 8:

Observer: JHeidt (LBTO), PHibon (LBTO), JHill (LBTO), DMiller (Tucson)
Telescope Operator: JHill (LBTO)
Telescope Support: JUrban (LBTO)
Instrument Support: JMorris (LBTO)
Adaptive Secondary Operator: MXompero (LBTO)

Summary

Good photometric night with 0.7"-0.9" seeing conditions

No telescope failures but a power failure at the end of the night (UT12:13)

At the beginning of the night, we took a set of data for Dave.

Took preset, guiding, collimation and offset (dice5) data.

Doug took a set of large offset data remotely from Tucson.

We also took dice5 data for Thomas (value=16, 32, 48).

Preset on StoneLagw - Large offsets test

09:04 pointto StoneLagw gs=12 PA=-90 TelM=active

09:13 Doug tests his new routine "large_stonel.pro" which uses the general "iif_large_offset.pro" and "irc_getseqimage.pro" to make large offsets of the field, but with the proper amount so a "new" star is visible on the IRTC. This special offset routine is needed because the IRTC is only 30" FOV but test of large offsets we what are for 1 to 5 arc minutes.

09:23 IDL> large_stonel, 5, retval with guide stars [25, 34, 27, 35, 22] where 25 is the star in the center of the field. We will make this pattern 5 times with IRTC cubes (2 sec x 30 images) after each
