Overview
========
This data set contains raw and reduced mid-infrared images of
comet 9P/Tempel 1, the target of the Deep Impact mission, obtained
by Y. Fernandez, C. Lisse, M. A'Hearn, and M. Belton using the
LWS instrument at the Keck I telescope. Images were acquired during
the night of 21 August 2000, about 7.5 months after perihelion.
This data set also includes a table of photometric results found
in the paper 'The nucleus of Deep Impact target Comet 9P/Tempel 1'
by Fernandez et al. 2003 [FERNANDEZETAL2003].
The LWS was operated in the chop-nod image mode. Observations were
made with filters centered at 4.8, 8.9, 10.7, 11.7, 12.5, 17.9 and
20.0 microns. Two bright-infrared standard stars, beta Andromedae and
phi 1 Ceti, were imaged for absolute flux calibrations.
This data set supports analysis of the size and albedo of the nucleus
of 9P/Tempel 1 for the Deep Impact mission.
Version 2 of this delivery volume includes some minor corrections to
file names and references in the catalog/ subdirectory.
Media Format
============
This data set is supplied as an electronic file and is formatted
