EPOXI EARTH OBS - HRIV CALIBRATED IMAGES V2.0

Metadata Updated: August 22, 2025

This data set contains calibrated, narrow band filter images (350-950 nm) of Earth acquired by the Deep Impact High Resolution Visible CCD (HRIV) during the EPOCh and Cruise 2 phases of the EPOXI mission. Five sets of observations were acquired on 18-19 March, 28-29 May and 04-05 June 2008 and on 27-28 March and 04-05 October 2009 to characterize Earth as an analog for extrasolar planets. Each observing period lasted approximately 24 hours. HRIV images were acquired once per hour with the filters centered on 350, 750 and 950 nm, whereas the 450-, 550-, 650-, and 850-nm data were taken every 15 minutes. During the observing period in May 2008, the Moon transited across Earth as seen from the spacecraft. On 27 September 2009 during the first attempt of an Earth south polar observation, only seven HRIV frames were acquired before fault protection turned that instrument off; the full sequence was successfully rerun on 04-05 October 2009. Version 2.0 includes the application of a horizontal destriping process and revised electronic crosstalk calibration files.
