The Pos-Targ warning is also what we intend in our proposal and is necessary for our testing. WFC3 UVIS CTE Monitor (star cluster) We monitor the Charge Transfer Efficiency (CTE) with changing epoch, varying target brightness, and varying image background. The aperture phometry-based CTE model and the empirical pixel-based CTE correction is derived and updated from the results of this proposal. NGC 6791 (a sparse cluster) and NGC 104 of 47 Tuc (a dense field) are the targets for this proposal, as these were the targets of former WFC3 CTE monitor proposals. This allows for comparison to former CTE loss and changing CTE with field density. NGC 104 has been observed with varying post-flash levels and with ACS, which allows for comparison between ACS/WFC3 CTE and changing post-flash. We propose these 8 orbits to continue the external CTE monitoring proposals starting in cycle 17. The varying post-flash was used to estimate the impact of post-flash on CTE mitigation, starting in cycle 20. When observed with filter F502N, the observation of NGC 6791 (a sparse cluster) and NGC 104 of 47 Tuc (a dense field) will monitor variation of CTE with field density. We dither long exposures by 2000 pixels vertically, so that the absolute CTE can be measured. Shorter exposures will provide a long to short flux ratio. With varying field density, post-flash, and exposure length, we build and maintain a CTE model based on many parameters. While historically the external CTE proposal was 3 epochs per cycle, the smooth and slow evolution of CTE degredation allows for fewer epochs. We observe NGC 6791 using F502N in pairs of exposure with a difference of 2000 pixels vertically dithered. As well as two long exposure pairs, one will have an applied post-flash of 12 electrons/pixel, which is the current reccomendation for CTE-mitigation. NGC 104 orbits have one long and one short pair of exposures with no post-flash. One short exposure pair with post-flash of 12, and the remaining eight long pairs of exposures have varied post-flash from 6-130 electrons/pixel. This background was estimated by Bagget & Anderson 2012 (HST WFC3 ISR 2012-12). Like NGC 6791 the difference in the pairs will be a dither of 2000 pixels. This proposals consists of eight total oribts over 2 epochs (4 per epoch) with 1 and 3 orbits on NGC 6791 and NGC 104 respectively per orbit. This proposal a continuation of external CTE calibration from 17 to now 26, including CAL/WFC3 proposals 11924, 12379, 12692, 13083, 13566, 14012, 14378, 14541, 14990. ------- Scheduling ------- The CTE long-term monitoring observations will be taken at two epochs in Cycle 26, starting six months after the latest Cycle 25 observations. The first epoch should be scheduled in January/February 2019, the second epoch in July/August 2019. We ask that both pairs of NGC 6791 and 47 Tuc observations (Visits 01-02, Visits 03-04) are taken within seven days from each other, to sample the CTE at similar epochs. We have set visit-level timing requirements for visit groups accordingly. ------ Calibration Justification ------- These data will be used to determine the rate of change of the CTE with time, and with position on the detector. Results will be compared to Cycles 17-25 CTE measurements for WFC3/UVIS CCDs, as well as to ACS/CCDs, and where possible to CTE measurements of first and second generation HST instruments. The analysis of the data will be used to continue calibrating a model of CTE-induced losses in both FLT and DRZ UVIS images, with a precision of better than 1% for stellar photometry and less than 5% for astrometric effects from CTE-induced source centroid shifts. The backgound levels, set through post-flash in some exposures, will allow to monitor the performance of post-flash to mitigate CTE. All exposures taken in this program will also be used to test the pixel-based UVIS CTE correction algorithm developed by J.
