12717( 2) - 02-Sep-2011 12:27:21 - [ 1] HUBBLE SPACE TELESCOPE OBSERVING PROGRAM 12717 Version: 2 Check-in Time: 02-Sep-2011 12:27:21 STScI Edit Number: 1 Title COS FUV Internal/External Wavelength Scale Monitor ------------------------------------------------------------------------------------ Type Cycle CAL/COS 19 ------------------------------------------------------------------------------------ Investigators Contact? PI: Dr. Cristina Oliveira Space Telescope Science Institute ------------------------------------------------------------------------------------ Abstract This program monitors the offset between the internal and external wavelength scales: this offset is referred to as "DELTA" in the wavelength dispersion reference file and corrects for the shift between the WCA and PSA in TV03 versus the shift between the WCA and PSA in orbit : (WCA-PSA_)_TV03 - (WCA - PSA)_orbit. Analysis of TV data indicates that this DELTA (offset) is cenwave and FPPOS independent for a particular grating, but it is grating and stripe dependent. To verify and monitor this, this program observes some cenwaves at different FPPOS. ------------------------------------------------------------------------------------ Observations Description ------------------------ This program monitors the offset between the internal and external wavelength scales: this offset is referred to as "DELTA" in the wavelength dispersion reference file and corrects for the shift between the WCA and PSA in TV03 versus the shift between the WCA and PSA in orbit : (WCA-PSA_)_TV03 - (WCA - PSA)_orbit. Analysis of TV data indicates that this DELTA (offset) is cenwave and FPPOS independent for a particular grating, but it is grating and stripe dependent. To verify and monitor this, this program observes some cenwaves at different FPPOS. 3 visits with G130M + G160M, using SK 191, each visit to execute every 4 months. 3 visits with G140L using NGC330-B37, eacg visit executing every 4 months.
