A baseline image set will be established by obtaining one internal flatfield in each IR filter using the channel's default lamp, plus one dark in each of the different sample sequence types used. Separate proposals will obtain additional darks and flatfields in each filter for CDBS reference file generation (proposals 11447 and 11433) and verify the health and flux output of the spare tungsten bulb for the IR channel (proposal 11543). This proposal corresponds to WFC3-10; it should not be run until after successful completion of the IR functional (WFC3 -07, proposal 11420) but Proposal 11423 (STScI Edit Number: 5, Created: Tuesday, July 1, 2008 8:05:19 PM EST) - Overview needs to be completed before execution of the initial IR alignment (WFC3-12, proposal 11425). OBSERVING DESCRIPTION One internal flatfield will be taken in each IR filter using the default tungsten lamp for the IR channel along with one dark in each of the sample sequences employed. This will exercise the filter wheel, providing a check of the wheel operation as well as an initial set of flatfields for comparing to thermal-vacuum ground test data and to later on-orbit data. CALIBRATION JUSTIFICATION Flatfield illumination patterns will be analyzed and compared to previous ground test results to check for any changes in filter structures, vignetting within field, etc. The flux level of the tungsten lamp will be compared to previous ground test results to verify performance of the bulb. Data will be used, along with internal flats and darks from other proposals, to generate updates for calibration pipeline flatfield reference files. ADDITIONAL COMMENTS Exposure times assume that tungsten lamp #2 is the default IR channel lamp. 2 Visit Proposal 11423 - Visit 01 - IR FSM Test Proposal 11423, Visit 01, implementation Diagnostic Status: No Diagnostics Scientific Instruments: WFC3/IR Special Requirements: GROUP 01,02,03,04 WITHIN 2D # Label Target Config,Mode,Aperture 1 tungsten flat TUNGSTEN WFC3/IR, MULTIACCUM, IR field Exposures 2 3 4 5 WFC3/IR, MULTIACCUM, IR tungsten flat TUNGSTEN field WFC3/IR, MULTIACCUM, IR tungsten flat TUNGSTEN field WFC3/IR, MULTIACCUM, IR tungsten flat TUNGSTEN field WFC3/IR, MULTIACCUM, IR tungsten flat TUNGSTEN field WFC3/IR, MULTIACCUM, IR Spectral Els.
