12807( 3) - 05-Jun-2012 20:10:35 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 12807 Version: 3 Check-in Time: 05-Jun-2012 20:10:35 STScI Edit Number: 1 Title Second COS FUV Lifetime Calibration Program: Verification of FUV BOA Operations (FCAL4) ------------------------------------------------------------------------------------ Type Cycle CAL/COS 19 ------------------------------------------------------------------------------------ Investigators Contact? PI: Dr. John Henry Debes Space Telescope Science Institute CoI: Dr. Alessandra Aloisi Space Telescope Science Institute N ------------------------------------------------------------------------------------ Abstract This program will obtain one external orbit of G191B2B, a previous SMOV4 BOA target. We will obtain spectra in the G130M, G160M, and G140L gratings at one cenwave each to 1) spot-check spectral performance, 2) obtain spatial profiles, and 3) complete updated target acquisition parameters. We will also test auto- wavecals within a BOA observation. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will acquire using NUV/MIRRORB+BOA aperture imaging, then proceed to take exposures at G140L and G160M with the autowavecal off. Finally we will take more detailed exposures at G130M at all 4 FP-POS and with auto-wavecal enabled to enhance the ability to characterize spectral performance.

We then take moderate S/N (~7-15) observations at G160M to obtain spatial profile information and TA parameters. Finally we take higher quality G130M data to spot check resolution, spatial profile information, and TA paramters, followed by a WAVECALS at each grating during occultation. For very accurate TA parameters we would Ideally want to include concurrent WAVECALS at every grating position to account for any possible drifts in the OSM, but this provides prohibitively high overheads. Since previous SMOV BOA operations found little difference in terms of parameters between G160M and G130M, and we expect very small drifts within an orbit, this strategy should be sufficient to provide adequate accuracy to the TA parameters. ISM/photospheric lines at G130M should provide a decent handle on how big drifts might actually be.
