PI: Brian Espey University of Dublin, Trinity College CoI: Jessica Kim Space Telescope Science Institute Y ------------------------------------------------------------------------------------ 5. Abstract Test the repeatibility of the slit wheel by taking a sequence of comparison lamp spectra with grating G230MB (2697) and the three smallest long slits (52X0.2, 52X0.1, and 52X0.05). This is a clone of Cycle 9 Program 8855. ------------------------------------------------------------------------------------ Observations Description ------------------------ Verify the repeatability of the slit wheel for 3 STIS slits (52X0.2, 52X0.1, and 52X0.05) by taking images with the Pt/Cr/Ne LINE lamp and the CCD detector. Use the G230MB (2697) grating with the CCD, and rotate the slit wheel among the 3 chosen slits. Detector: CCD Grating: G230MB (2697) Slits: 52x0.2, 52X0.1, 52X0.05 Grating A: 52X0.2 (10 seconds) Grating B: 52X0.1 (10 seconds) Grating C: 52X0.05 (20 seconds) Sequence: A-B-C-B-C-A-A-B-A-C-B-B-A-B-C-B-C-C-A-B-A-C-B -A Forward motion: B -
