Obtaining TUES data

The TUES Archive is maintained at the Space Telescope Science Institute (STScI) as part of MAST, the Multi-mission Archive at STScI. The data are stored on spinning disk. Data may be found and retrieved in any of 3 ways: searching the TUES database, browsing the TUES catalog, or anonymous ftp.

Normally web users will search the TUES database for particular files using the TUES search page. The returned table of found entries allows the user to mark the images to be downloaded. A request for data begins a retrieval job. Once the requested files are located, they are written to a data distribution disk area on the system, bundled into a tar, zipped format file, and downloaded to the disk area specified by the user in the "save as..." pop-up window. The files have finished downloading when the pop-up window disappears. If several observations are requested, the wait time will be proportional to the number of images requested.

Alternatively, one may proceed to the TUES catalog, Pick an object category and click on object names or datasets. Clicking on the object name brings up a preview window depicting the image. Clicking on datasets

Primary access is via the web although FTP access is also possible using either a web browser (i.e., or, as explained below, using anonymous ftp from an ordinary terminal with network access. As no file conversions are currently available via ftp, returned files are sent individually, in gzipped compressed mode. The the data are grouped by dataset name (e.g. tues6003_1_5), so you would need to know the dataset of interest.

As an example, a typical interactive ftp session to retrieve files for tues6003_1_5 would be:

cd /pub/orfeus/tues/data/
cd tues6003_1_5
mget *

Accessing the data via anonymous ftp is a good alternative for users who wish to obtain only 1 or 2 files per dataset.
