Downloading data from the archive

• To retrieve the required ISGRI analysis data from the archive, go to the following URL:

  http://www.isdc.unige.ch/integral/archive

  You will reach the W3Browse web page which will allow you to build a list of Science Windows (SCWs) that you will analyse with OSA.

  • Type the name of the object (4U 1700-377) in the `Object Name Or Coordinates' field.
  • Do not forget to change `Search Radius' if you are interested in science windows where your source is in the partially coded field of view. Set it to e.g. 10 degrees instead of the default 5 degrees = 300 arcmin.
  • Click on `More Options' button at the top or at the bottom of the web page.
  • Deselect the `All' checkbox at the top of the Catalog table, and select the `ScW - Science Window Data' one.
  • Press the `Specify Additional Parameters' button at the bottom of the web page.
  • Introduce values in the fields of interest. For instance:
    • Sort output by `scw_id', for that check the `Sort' column.
    • Put `pointing' in the field `scw_type' (to specify that only pointings should be returned and not slews)
    • Put ` 2003-03-15T23:00:00' in the field `start_date' and put ` 2003-03-16T02:30:00' in the field `end_date' (no spaces should be present).
    • Put public in the field `ps' (to specify that only public ScWs should be returned).
    • Put 100 in the field `good_isgri' (to select Science Windows with good ISGRI time higher than 100 seconds)
    • Press the `Start Search' button at the bottom of the web page. In our case, a table with 5 ScWs will be displayed.
    • Select the ScWs of interest. To follow the example in the Cookbook click on `All' (for all ScWs).
    • Press the `Save ScW list for the creation of Observation Groups' button at the bottom of that table and save the file with name `isgri_gc.lst'.

  This file `isgri_gc.lst' will be used later as input for the og_create program (see Section ). From this file you need the four lines below either in the format as given above or simple as:

  005100430010.001
  005100440010.001
  005100450010.001
  005100460010.001
  

  You should then download them 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 get per e-mail a link to the required script to get your data and the instructions for the settings of the IC files and the reference catalogue. Just follow these instructions.

• To retrieve the required PICsIT analysis data from the archive proceed in the same manner with the following parameters:
  • `Object Name Or Coordinates' : Crab
  • `Search Radius' : use default value
  • `scw_id' : 0039% (To select only science windows starting with 0039)
  • `start_date' : 2003-02-07T06:44:19 and `end_date': 2003-02-07T12:44:05 and save your results in a file called `picsit.lst' which should contain:

    003900020020.001
    003900020030.001
    003900020040.001
    003900020050.001
    003900020060.001
    

You can see below in Section , an example of downloading data directly from the command line.
