For most of the pipeline steps the system contains at least one alternative which might be highly interactive or simply an improved pipeline module which has been given to the IA 3 system for test. Sometimes even pure IDL might do the job. The user can specify the calibration files they want to use before starting the pipeline command by a GUI select calfile tool. Here the user specifies to use the actual pipeline, test or a self defined calibration file. But the user has also the possibility to specify calibration files on the command line level within the call of the pipeline module.
Improvements are under development.
IA 3 tools to a subset IA 3 system which is basing purely on IDL and gives significant support of scientific work on SWS data. This subset will be distributed. Finally it is under investigation to switch to IDL version 5.
