Project 1640 Design and Operations
Align Pupils using bright sky (pre-sunset) tweak cass ring angle to align spiders
Obtain on-telescope Hg lamp data to check for flexure/lambda changes
Check pupil cam sensitivity with dome lights
Verify and Calibrate ADC performance
ADC calibration. motor rotation algorithms need to be verified, and scale
factor determined (5 bright stars at airmasses of 1.0 to 1.56)
Test for pupil wander (5 airmasses, 5 HAs) also tests for instrument flexure
Verify star acquisition: occulted images
Acquire multiple sky flats
July 9, 10 (observing):
Morning: Acquire suite of on-telescope darks and additional dome flats
Astrometric and photometric data quality verification
HIP 101769 - RA 20h38m, sep 0.44", V_primary = 3.64, delta V = 0.91
HIP 102531 - RA 20h47m, sep 0.22", V_primary = 4.27, delta V = 0.88
Spatially Resolved Spectroscopy Data verification:
Uranus and Neptune (e.g. methane chemsitry across FOV)
Disks: HD 141569A(7th mag), DoAr 25 (9th in J, 12.65 in R), Vega (0th)
Acquire non-AO corrected G star flats (do we need to implement G-star flat
mode on FSM to raster the star?
Magnitude Limits and FSM tracking limits:
Vega, short and long exposures occulted
5 stars at 2, 5, 8, 10 and 13th mag (V)
FOV Distortion and initial coronagraphic performance:
Crowded Field (Barnard’s star, Doradus Deep Field?)
Coronagraphic performance as function of V magnitude
Young stars: Altair , Rasalhague (type A, additional binary position)
HIP98767, other high priority targets from Lyot Project
Continue with science observations.
Verify and Implement data backup procedure
July 11: Assist with Instrument removal and storage
Modify removal procedure as needed
Departure noon
