Transcript 2010A P200 Statistics, Triplespec Status

A Handful of Topics
P200 Constituencies
• We re-negotiated our
partnership agreements in
CY2009
• Long-standing partners
JPL and Cornell are
continuing as partners (for
five and three years
respectively)
• New partner NOAO joins
at 1/16 share with
particular interest in
(single-object)
spectroscopy. Time for
NOAO participation
coming from decreasing
Cornell commitment
• Oxford partnership
ongoing…
P200 Instrument Usage/Trends
• P200 Instrument Usage
for 2010A and 2009B
• Majority (~ 55%) for
spectroscopy
• AO usage increase:
expectation of bench
removal in 2010A
• P1640 99-night survey in
2011 – 2013 inclusive
• Structural decrease in
OSWIFT with LGS
decommissioning

Instrument Usage/Trends (Cont)
• Constituency Trends:
– AO Usage PRESENTLY
tilted toward JPL
constituency; this changes
structurally with the 99night P1640 program
– CIT (80%), Cornell
(100%), & NOAO (100%)
constituencies tend toward
spectroscopic use
– Concern: no non-Oxford
participation in OSWIFT
science (1 CIT night in
09A)

TSpec Update
•
TSpec is an important near-IR
spectroscopic capability at P200;
prominent nationally (i.e. NOAO
listed as instrument to emulate at
Kitt Peak – NOAO Town Hall DC)
•
TSpec has had its share of
electronics problems – which
appear to be behind us – thanks
to GustavoR’s extensive support
in 2009
•
A significant number of user
reports of TSpec control software
crashed (guider GUI)
•
JHickey & MBonati have made
simplifications to guider GUI; in
recent TSpec (e.g. late Dec) runs
software has been considerably
more reliable

COO Operations SW Engineer
• However, we anticipate there are still
TSpec issues to iron-out, so…
• Creating campus position to focus on
Palomar operations instrument control
software support (co-located with OIR)
• Initial concentration on TSpec and DBSP
control software
• Job ad submitted to PMA this week;
expect start date in April.
2010B Solicitation Dates
• 15 Feb – Call for engineering proposals
• 26 Feb – Engineering proposals due
• 8 March 2010 – Science solicitation
released
• 2 April – Science proposals due
• 19 April – TAC meeting
• 3 May – CIT inputs due to WMKO

Mirror Support Background & Recent History


In mid-2007 severe image distortions were experienced for an
extended period of time.
Significant improvement was observed after vigorous exercising of
the mirror supports in lateral mode.

A.O. system DM was in a flat state, Aug.
2007.

Recent image quality issues
More recently, occasional bad images are reported by telescope operators that are
resolved by moving the telescope to a different place in the sky and then returning
to original target.
