Doecslit ‘sparams’ and Apall parameters

Ian Roederer wrote on Jun 05, 2006

Hello,

I have been using the DOECSLIT task to extract echelle spectra. I have tried to adjust the parameters for the trace using the 'sparams' within DOECSLIT, but with no success in extracting my spectra the way that I want. When I look at the parameters available for the trace in the APALL task, there are several additional ones available, such as t_nsum and t_nlost.

Is there a way to access (and adjust) these additional parameters when running DOECSLIT, or will I need to use APALL and other tasks to extract my spectra?

Thanks very much,
Ian

Frank is the best person to answer this, however there is a hidden pset called APSLITPROC that might be useful. See

cl> epar apslitproc
cl> ?_                           # list hidden tasks

You might also search the forums for a similar question and earlier reply. Hope this helps.

Cheers,
-Mike

Hi Mike,

The APSLITPROC parameter set worked nicely. Thanks for your help.
