DATA_SET_DESCRIPTION Global Imaging Campaign to Observe the Shoemaker-Levy 9 Impact Phenomena. Data Set Overview : A global imaging campaign (GIC) was organized at sites during the impact of comet Shoemaker-levy 9 with Jupiter. These five sites were Queensland in Australia, the Cerro Tololo Interamerican Observatory, Lick Observatory, Mauna Kea Observatory and Reunion Island. All sites used a combination of high speed optical CCD systems with similar broad and narrow band filters. Data : The coordinated efforts covered a few days prior to the first impact and ended at least 5 days after the last impact. The collection of images were taken through the series of filters to monitor the morphology and development in the Jovian atmosphere as the impacts continued. Another goal was to search for transient events at the impact sites; most sequences through the methane (8900 Angstrom) filter did not show change. A total of 12617 images have been submitted from the five sites as follows: Australia 4002 CTIO 5284 Lick 426 MKO 1378 Reunion Island 1527 Processing : The data has not been processed beyond the original collection. For the submission Lowell observatory staff cropped the images to yield about 50 arcsec image. This resulted in the following correspondence of image size and pixel scale: Australia : 120 x 120 at 0.40 arcsec/pix CTIO : 96 x 96 at .534 arcsec/pix Lick : 92 x 92 at .55 arcsec/pix MKO : 92 x 92 at .55 arcsec/pix Reunion Island : 124 x 124 at .376 arcsec/pix The orientation was not well specified by the keywords CROTA1 and CROTA2; for the images from Australia, the image orientation shifted by 10 degrees while for Lick Observatory, some images had shifted by 90 degrees in a non-consistent manner. Media/Format : The data are written into a CD or DVD volume, and are also available on-line.

CONFIDENCE_LEVEL_NOTE Confidence Level Overview : A global imaging campaign (led by Lowell Observatory) got data from five remote sites, which were then reprocessed at Lowell to provide a consistent set of images, approximate in size and pixel scale. At that time, the orientation was provided in terms of keyword values for CROTA1 and CROTA2. There is a slow change to these values over time for most data; however, in a few cases, the Australian data shows an abrupt change by at least 10 degrees, and for the Lick data, these changes are as much as 90 degrees. No suitable explanation for these changes is known. Consequently, the orientation of these data should be used with caution. These data were peer reviewed on 6 December 2002.
