The below example is based on observations of the Crab from Revolution 102. To retrieve the required analysis data from the archive, go to the following URL:
http://www.isdc.unige.ch/integral/archive#Browse
The web page offers the tools that will allow you to build a list of SCWs needed to create your observation group for OSA.
At this point, you should be at the Query Results page with all the SCWs available for revolution 102. Sort the ``Scw_id'' column by clicking on the left arrow below the column ``Name''. You can then select the SCWs we are interested in, i.e.,
010200200010 010200210010 010200220010 010200230010 010200240010 010200250010 010200260010 010200270010 010200280010 010200290010
Press the ``Save SCW list for the creation of Observation Groups'' button at the bottom of that table and save the file with the name ``spi.lst'' in your analysis current directory (i.e., $REP_BASE_PROD as explained above). The file ``spi.lst'' will be used later as an argument for the og_create program. In this file you find the lines
scw/0102/010200200010.001/swg.fits[1] scw/0102/010200210010.001/swg.fits[1] scw/0102/010200220010.001/swg.fits[1] scw/0102/010200230010.001/swg.fits[1] scw/0102/010200240010.001/swg.fits[1] scw/0102/010200250010.001/swg.fits[1] scw/0102/010200260010.001/swg.fits[1] scw/0102/010200270010.001/swg.fits[1] scw/0102/010200280010.001/swg.fits[1] scw/0102/010200290010.001/swg.fits[1]
which is the list of DOLs (Data Object Locators) of the Science Window
Groups you want to analyze. The DOLs include the path and name of the
FITS file, and the location of the SWG grouping table inside the file
(remember that a FITS file can include more than one table, or image,
arranged in a number of extensions). For example, the last DOL in the
above list indicates a SWG located in the first extension of the FITS
file "swg.fits" lying in the directory
"scw/0102/010200290010.001/".
You can download the data pressing the ``Request data products for selected rows'' button. In the ``Public Data Distribution Form'', provide your e-mail address and press the ``Submit Request'' button. You will be e-mailed the required script to get your data and the instructions for the settings of the IC files and the reference catalogue.
