The following files are found in this directory. CALINFO.TXT - This file. aeffLAMP_001.fit - Effective aperture area correction data. aeffLAMP_001.lbl - Detached PDS label for aeffLAMP_001.fit. darkLAMP_001.fit - Dark correction image for histogram data. darkLAMP_001.lbl - Detached PDS label for darkLAMP_001.fit. flatLAMP_001.fit - Flatfield calibration image. flatLAMP_001.lbl - Detached PDS label for flatLAMP_001.fit. Notes on Using the Calibration Files ==================================== The dark correction for pixellist mode data is applied at the stage of mapping the detected UV photons, and thus is not applied even at the RDR level. However, a measure of the dark signal detected is recorded in the RDR file. The deadtime and wavelength calibrations are applied directly in the LAMP-MIKE code that generates the LAMP RDR files from the EDR files. The effective area and flatfield calibration files included in this directory are input to the LAMP-MIKE code that generates the RDR output file from the EDR input file.
