WFC G800L aXe Products

To use these calibration products with aXe, copy them into a directory and set your AXE_CONFIG_PATH environment variable to point to that directory.

aXe Downloadable Files

The sensitivity files were last updated Jan 2008 and are applicable to all data taken so far. Details can be found in STECF ISR 0801.

All of the below files are available for download via ftp at ftp://ftp.stsci.edu/cdbs/acs_aux. Please remember that the sensitivity files are FITS TABLES and need to be opened with appropriate software.
