A new version of APT (12.3) was released on 7/10 fixing 81 OPRs, and the followup version 12.3.1 was released on 7/17 fixing issues with wholly internal orbits. Please note: the official release notes for APT were sent to "apt-users" and "apt-interested" distribution lists. If you have subscribed to the rps2-users list in the past we would suggest signing up for apt-users. (You can do this from: http://www.stsci.edu/cgi-bin/jDomo.tcl) Training videos, manuals, and other information regarding APT are available at http://www.stsci.edu/hst/proposing/apt WFPC2 Header Astrometry and UCHCOORD -J. C. Hsu The UCHCOORD task was initially provided to the community to correct WFPC2 astrometry due to a number of aperture parameter updates that took place during the early years of WFPC2 operation. Since the implementation of On-The-Fly-Reprocessing (OTFR) in May 2001, all WFPC2 data retrieved from the archive, regardless of its observation date, has had these corrections applied automatically before being delivered, thus we have discouraged running the UCHCOORD task on OTFR data since it is no longer needed (as described in WFPC2 STAN 45, March 2001 by Baggett, Hsu & Gonzaga). It was expected that modifications to the UCHCOORD task enabled it to discriminate between old and new OTFR data, such that it would not perform astrometric corrections on any OTFR data, if it were inadvertently run (for example, Section 4.3.3 in WFPC2 Data Handbook, Version 4.0, 2002, S. Baggett et al.). However, it has recently become apparent that the UCHCOORD task may still modify the astrometric information in image headers even when the data are retrieved via OTFR, since the keyword expected by UCHCOORD ("PROCDATE") does not match the keyword provided by OTFR ("PROCTIME"). We thus caution observers that it is likely that the UCHCOORD task has always incorrectly modified astrometric information in images retrieved via OTFR if it were run on such data. Now that this issue has been identified, we have implemented the correction to it in the UCHCOORD task, and this corrected version will be available in the next official version of STSDAS, scheduled for September. We remind users that it is no longer necessary to run the UCHCOORD task on any WFPC2 data that is retrieved via OTFR, and we recommend that any old WFPC2 data should rather be re-retrieved via OTFR since many other calibrations are also improved. However, the new version of UCHCOORD will now correctly check whether or not the images have been processed through OTFR in case it is inadvertently run on such data, and will no longer modify the header astrometric keywords in such cases. WFPC2 Cycle 12 Calibration Planning -Anton Koekemoer The WFPC2 Cycle 12 Calibration Plan is currently being finalized. It contains two principal components: continuation of long-term monitoring, and special Close-Out programs. The long-term monitoring programs include the regular decontaminations, filter throughput checks, darks, biases, internal flatfields, Earthflats, and CTE monitoring. Some of these are scaled back compared to previous cycles, to account for the reduced WFPC2 usage during Cycle 12. Our special Close-Out Calibration programs incorporate feedback that we have received from the community, and include UV astrometric characterization, narrow-band/LRF central wavelength checks, and photometric cross-calibration aimed at improving the direct tie-in between the WFPC2 filter set and other photometric systems, most notably those of ACS, WFC3 and SDSS. We encourage any interested members of the community to contact us with further suggestions for WFPC2 Close-Out calibration that could be performed either in this Cycle or the next Cycle. We remind the community that Cycle 13 will likely be the last Cycle for WFPC2 observations before it is replaced with WFC3, thus we welcome any suggestions from the community on calibration observations that may be carried out to improve the overall scientific value of the rich archival legacy left by the past decade of WFPC2 operations. Toward a Multi-Wavelength Geometric Distortion Solution for WFPC2 -V. Kozhurina-Platais, J. Anderson, A. M. Koekemoer The goal of an astrometric calibration of HST WFPC2 is to obtain a coordinate system free of distortion at the level of precision of 1 mas. So far such calibration has been done only for the wide bandpass F555W filter. The inner calibration field of w Cen exposed through filters F300W, F555W and F814W has been used to examine the geometric distortion of WFPC2 as a function of wavelength. The improved PSF-fitting technique by Anderson and King has been used to obtain the working sets of x,y coordinates for stars in assorted HST WFPC2 frames with the globular cluster w Cen in these three band-passes. We used a bicubic polynomial model to derive geometric distortions in the F300W and F814W filters relative to the distortion-free coordinates in the F555W filter. For each filter, four sets of distortion corrections, corresponding to each of the four WFPC2 chips, have been optimized independently. The main conclusion of this study is that the difference in the amount of distortion in the F300W filter is about 3% higher than in the F555W but in the F814W filter it is about 1% smaller than in the F555W. Tables with distortion coefficients are also presented. +----------------------------------------------------------+ | Recent WFPC2-related Papers/Preprints +----------------------------------------------------------+ We draw your attention to these papers, based on WF/PC and WFPC2 data, that have appeared since the last STAN, or will appear in the next few months.
