Spectroscopy: Data Reduction Recipes
|
|
The following tables describe the UIST spectroscopy ORACDR
recipes; click on the recipe name for more information.
The Requirements listed below are frames that should be obtained
prior to use of the recipe, although data can always be re-reduced
when the appropriate frames have been taken. Flats and standard stars must
be obtained through the same grism and slit.
