Previous WFPC2 Advisories

09/20/2005: Important WFPC2 Closeout Information.

07/15/2005: SYNPHOT Data User's Guide has been released.

A new WFPC2 Memo has been issued regarding WFPC2 Filter Wavelengths in the HST Archive. Due to discrepancies between the "Central Wavelength" and other filter quantities, it has been decided to replace the use of "Central Wavelength" with the use of "Pivot Wavelength" instead. For details please follow the link.

A new paper on An Improved Distortion Solution for HST's WFPC2 by Jay Anderson and Ivan King is available as a preprint (PostScript, 4.4MB). The paper should appear in the Jan 2003 version of the PASP. There is also a text file containing a Fortran routine that implements the distortion solution.

A new edition of the WFPC2 Data Analysis Tutorial, a step-by-step guide to reducing WFPC2 data (Version 3.0 - July 2002) is available in PostScript (3.8 MBytes) and PDF (1.0 MBytes)!

Outsourcing Candidates for WFPC2.

16 May 2001: Do not run UCHCOORD on new data retrieved through OTFR. This is no longer necessary, as OTFR now updates the astrometric information automatically. See this STAN (May 2001) for details.

Important note for dither package users who recently installed STSDAS V2.3.

Complete information on the WFPC2 Shutter Anomaly (PDF, 4.8 MB). Older updates are still available.
