Performing Batch Reduction

The Batch Reduction window allows catalogs of observations to be processed and a data reduction scheme to be defined dynamically. The different steps like Bias, Dark, Flat-Field correction, etc. are optional and must be set by clicking on the option buttons located on the left side of the window. The option button turns green when selected.

For each selected reduction step, the corresponding parameters must be provided, as indicated in the short help section. These parameters can be saved in a parameters file and be restored later, using the pulldown menu.

The text fields associated to images, tables or catalogs allow a selection list to be displayed using the right-hand mouse button. Clicking over the desired name updates the corresponding field.

The input files can be given in two ways:

• Catalog name: by providing a catalog name in the field Prefix/Catalog
• Image numbers: by indicating the prefix of the images in the field Prefix/Catalog and providing the image numbers in the field Numbers, using dashes and/or commas. as in:
  Prefix/Catalog : red
  Numbers: 3-5,8
  In this example, the images red0003, red0004, red0005, red0008 will be processed.

The dialog form accessed by pressing "Airmass ..." allows to modify the airmass values of the input images. If any of the input images do not have the corresponding airmass descriptor, the airmass dialog form is displayed automatically. The button allows the modification of the airmass values of the input images. The button executes the batch reduction.
