WFI@MPG/ESO2.2m THELI Test Data Set
===================================

This README briefly describes how to process a WFI test data set
with the 'command line' version of THELI. It does not introduce
methods and algorithms but merely concentrates on how to run the
programs.

1. The data set we use for our demonstration purposes is
   (very) briefly described here:

   http://marvinweb.astro.uni-bonn.de/data_products/THELIWWW/THELI_tut/THELI_wfi_testdata.html

2. Instead of retrieving the data from ESO and building up the necessary THELI
   directory structure you can retrieve the images here:

   http://marvinweb.astro.uni-bonn.de/data_products/THELI_WFI_TESTDATA/

   Please preserve the structure of the provided files when downloading
   them.

3. The downloaded files are (Rice) compressed. To uncompress them use the
   script 'compress.sh' that you downloaded with the data. See the script
   itself for more info.

4. If at any stage of your processing you want to go back to the original
   file structure, use the script 'cleantest.sh' which is also within
   the data package.

5. Install the command line version of THELI.

6. Create a THELI 'reduce' directory fron which you will later launch
   all processing tasks. Please read the page

   http://marvinweb.astro.uni-bonn.de/data_products/THELIWWW/THELI_tut/THELI_concepts.html

7. The script 'do_WFItestdata.sh' within the data package contains all
   necessary data processing steps. Copy it to your 'reduce' directory. Do
   the same with the file 'Stetson_std_2.0.cat' (Stetson photometric standard
   star catalogue).

8. Have a look at the script 'do_WFItestdata.sh' within your reduce directory.
   You need to change some lines at the begining of the script.

9. I would recommend you to first comment all processing steps within this
   script and to consecutively uncomment / run / inspect.

10. Please ask at any time you have questions!
