They will be used to monitor WFPC2's flat field line_4: response and to build a high S/N flat field database. UV flat fields line_5: will be obtained with the cal-channel's ultraviolet lamp (UVFLAT) using the line_6: UV filter set (F170W, F160BW and F336W). The UV flats will be used to line_7: monitor UV flat field stability and the stability of the Woods filter line_8: (F160BW) by using F170W as the control. The VISFLAT/UVFLAT ratio from line_9: the F336W flat fields will provide a diagnostic of the UV flat field line_10: stability and tie the UVFLAT and VISFLAT flat field patterns to a line_11: common baseline. A VISFLAT exposure with the Woods' filter (F160BW) line_12: allows its visible transmission to be monitored. Two VISFLAT exposures line_13: obtained through the LRF (FR533N), one at each gain, provide a line_14: monitor of the ADC's performance. Histograms generated from the ramp line_15: filter flats will be used to trace the ADC transfer curve. Two line_16: supplemental dark frames are obtained with CLOCKS=ON for the purpose line_17: of calibrating science frames and monitoring the dark current rate line_18: for this mode of operation. The VISFLAT and UVFLAT exposures have been line_19: packed to optimize use of each lamp-on cycle. This proposal runs every month. ! ! end of abstract general_form_proposers: lname: CLAMPIN fname: MARK inst: STSCI country: USA ! lname: BAGGETT fname: SYLVIA inst: STSCI country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: These data are obtained to monitor: line_2: 1) Flat field repeatability with time through the main photometric line_3: filter set. The flat field data from this will be combined and used line_4: in the generation of high signal to noise flat fields. line_5: 2) the ratio of INTFLAT to VISFLAT flat fields through the same filter line_6: provides a monitor of the stability of the cal-channel tungsten lamps. line_7: 3) UV flats will be used to monitor UV throughout, the buildup of line_8: contaminants on the CCD windows and to generate higher signal to line_9: noise flat fields for UV observations, since the flux from individual line_10: UV flats is relatively low. line_11: 4) The ratio of F336W (VISFLATS)and F336W (UVFLAT) flat fields will be line_12: used to monitor the stability of the UV lamp and tie the UV flat line_13: fields to the visible flat fields. line_14: 5) The ratio of the F170W and F160BW will be used to monitor the Woods line_15: filter throughput. line_16: 5) The F160BW VISFLAT is used to monitor for an increase in the line_17: filter's red-leak. line_18: 6) The ramp filter flat fields are used to generate image histograms line_19: which can be used to monitor the transfer functions of the ADCs. ! question: 5 section: 1 line_1: This proposal runs every month. ! question: 8 section: 1 line_1: 1) Do not change order of UVFLAT and VISFLAT lamp exposures as they line_2: are packed to fit the ~40 minute calibration-lamp cycle time. ! !end of general form text general_form_address: lname: CLAMPIN fname: MARK category: PI addr_1: 3700 San Martin Drive city: Baltimore state: MD zip: 21218 country: USA phone: (410) 338-4711 ! lname: BAGGETT fname: SYLVIA mi: M category: CI addr_1: 3700 San Martin Drive city: Baltimore state: MD zip: 21218 country: USA phone: (410) 338-5054 ! ! end of general_form_address records !
