Software Tests

Adaptive Optics Tests

This are all very high priority as they are needed to have UAO ready for LUCI/AO commissioning.
from DMiller email of 4-Aug-2016

Nighttime per side:
\x97\x97\x97\x97\x97\x97\x97\x97\x97\x97\x97\x97
0.5 night - check operation of AO system using old AO Supervisor (CentOS 5).  We do
     not need LUCI images, but would be advantageous.
1 night - check operation of AO system using new AO Supervisor (CentOS 6/7).  We do
     not need LUCI images, but would be advantageous.
1 night - Familiarize LBTO personnel to the operation of the new UAO functionality. This time
     is needed so we are comfortable with UAO operation going into LUCI/AO Commissioning
     starting September 16th.  We do not need LUCI images, but would be advantageous.

**Note, the goal of this nighttime schedule is to first, make sure the AO system is ready for
     LUCI/AO Commissioning with the old AO Supervisor.  The hope is that we would be ready
     with the new UAO AO supervisor (CentOS 6/7) for LUCI/AO Commissioning.  If we have
     difficulties with CentOS 6 or 7 we could fall back to CentOS 5.
**Note, it should be possible to test both sides at the same time
**These 2.5 nights can be split into half nights, or a fews hours a time
**The preference would be have have AO nighttime testing as early as possible so we
     can determine if we can operate with UAO with CentOS 7 (preferred) or UAO CentOS 6
     or have to fall back to CentOS 5 (no UAO).
**The first 0.5 nights of testing with CentOS 5 should have reasonable seeing (<1.1" or 1.0\x94) to
     make sure AO system is working in stable conditions after the summer work.  The next
     2 nights could be worse seeing (<1.5\x94) for checkout of UAO CentOS 6.7 and familiarizing
     of LBTO personnel with UAO.

AO Commissioning Task:
\x97\x97\x97\x97\x97\x97\x97
2 x 4 hours - collect data for WUnit stage transformation.  One set to calculate transform and
     one set to confirm transform is good.

**Note, the Telescope calendar on the web for daytime and nighttime has not been populated for
      September.
**We are ready and expecting to be on-call for AO testing the first two weeks of September so
      we can be ready in a moment\x92s notice (well 30 minutes) to start AO work.
**For UAO testing we will request support from Arcetri (Alfio, Luca).  Second half of the night
      works better for the Italians.

Uses LUCI

Uses LUCI1

Uses LBC

  • Collect new binocular pointing data with LBC (priority=low, time=2hrs, seeing<2 arcsec, thin clouds OK)
