Are digital versions of the transmission curves available?Throughput component tables for all ACS observing modes are available in digital form. They can be found in the anonymous ftp directory:
> ftp ftp.stsci.edu Name: anonymous Password: firstname.lastname@example.org ftp> cd /cdbs/cdbs1/comp/acs
To make sure what files need to be retrieved from this directory, load synphot in an IRAF window, type "showfiles", and then any obsmode you are interested in, and hit return. For example:
cl> stsdas.hst_calib.synphot sy> showfiles acs,hrc,f220w #Throughput table names: crotacomp$hst_ota_007_syn.fits cracscomp$acs_hrc_m12_005_syn.fits cracscomp$acs_hrc_m3_005_syn.fits cracscomp$acs_f220w_004_syn.fits cracscomp$acs_hrc_win_005_syn.fits cracscomp$acs_hrc_ccd_010_syn.fitsThe complete list of all throughput tables being used for that observing mode is given. These tables can be retrieved from the anonymous directory above described.
