Abstract • The absolute photometric calibration of the Hubble Space Telescope (HST) in the UV will be based on low-dispersion spectra obtained by IUE. Therefore, these data must be corrected for the substantial changes observed in the sensitivities of the IUE SWP and LWR cameras. A previous paper specified the correction in 5 A bins for SWP through 1986.36. This paper details the corrections for LWR and provides an update for SWP through 1987.36. A total of 764 LWR spectra of five standard stars are analyzed to derive the annual change spectra for the the low-dispersion observing modes.
