On July 4 (UT), the Deep Impact spacecraft intercepted comet Tempel 1. Director's time at the W. M. Keck Observatory was allocated in order to observe the comet with the High Resolution Echelle Spectrograph (HIRES) on Keck 1, as well as the Near Infrared Spectrometer (NIRSPEC) on Keck 2.
These data comprise the first public release of data from the Keck Observatory Archive (KOA), which will begin publicly serving non-proprietary HIRES data in February 2006.
The data are also available from the W. M. Keck Observatory's Deep Impact Observations site.
For help downloading HIRES and NIRSPEC Deep Impact observations, please see the download user's guide, or contact the KOA Helpdesk.
