I'm wondering if anybody here has spent any time working on the Tempel 1 images from Deep Impact. The data are available at the Small Bodies Node (see e.g. http://pdssbn.astro.umd.edu/holdings/dif-c...0/dataset.html), and Version 2 of the PDS archive (which appears to have been published 3 years ago) includes versions of the data that have been calibrated, cleaned of instrument artifacts, and converted to units of radiance and also I/F. The HRI data have not been deconvolved to remove the blur: a bit of playing shows that without deconvolution, HRI images look pretty similar to MRI images. Attached is a color composite I made of the highest-resolution full-globe shots of Tempel 1 captured by the MRI before the impact. The image isn't big but there's more variety in color than I expected. This is made from the I/F images and is an RGB composite of red, green, and violet continuum filter images, overlaid over a clear image that I sharpened slightly. It's very red, but I think that's real.
Has anybody else worked with these? -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
