Data Reduction Frequently Asked Questions
How can I 'extract' lines from the arc and match them to wavelengths?
In order to run the isaac_spc_arc recipe, you also need to select the CALPRO_XE_CATALOG and CALPRO_AR_CATALOG files (see pipeline manual page 48), which correspond to fits files named something like M.ISAAC.2008... in your data directory. These files should have been downloaded through the CalSelector option. In gasgano, you can find them listed in "Unknown Program/Unknown Observation". Then, the recipe should no longer crash.
