||
Accessing the ROSAT Data Archives |
||
1. Through GSFC "Browse" |
||
| 2. Through the ROSAT All-Sky Survey (RASS) | ||
1. Through GSFC "BROWSE" A query on the coordinates 14h02m48s, +09d19m40s for data from ROSAT, the ROSAT All-Sky Survey and the ROSAT Pointed Source Catalogs gives this query information page stating that it queried 69 tables and 13 rows were returned in seven catalogues (in red on the page). It also gives thumbnails of the Digital Sky Survey (DSS) Optical Image and the ROSAT All-Sky Survey (RASS) X-ray Image. |
 |
|
| The "Query Results" tab lists the telescope (one tab for ROSAT in this case) and tabs for each catalog listed in red on the Query Information tab. Here they are the ROSATArchival Data (rosmaster), All-Sky Survey Archival Data (rassmaster), Catalog PSPC WGA Sources (wgacat), Results Archive Sources for the PSPC (rospspc), Complete Results Archive Sources for the PSPC (rospspctotal), Archival WFC EUV Data |  |
|
| (wfcpoint) and the Observation Log (rosatlog). Clicking on each tab allows one to select each row of data. | ||
The "Data Products Retrieval" tab is where the selected data can be retrieved. The tables show which data products have been selected. At the top, the "Preview and Retrieve" gives more information about the actual products (ASCII, FITS or GIF files with thumbnails of the latter) in each row of data under the various tabs on the "Queary Results" Page. To create a TAR file of the data, either select rows or click on "Select all products for all rows" at the top, scroll to the bottom and click "TAR selected products" OR, back on the "Data Products Retrieval" page, the "Retrieve" button creates a tar file with all the data selected, gives the size of the tar file and a link from which it can be downloaded. |
