Interactive Analysis (IA) will be used by SOT members at the SOC and by support members at the home institutes. For the general observer, it is of importance only through the derived calibration data and the refinement of pipeline algorithms. IA consists of a series of modules (programs or procedures) running under IDL. One part of IA is created by porting the DERIVE_SPD and AUTO_ANALYSIS modules to the IA environment. These modules are then used together to have the SPG functionality under IA, but also individually to be able to e.g. subtract only dark-current data from SWS measurements. IA will allow access to data from any stage in the DERIVE_SPD and AUTO_ANALYSIS pipeline. This data may be ERD, SPD, AUTO_ANALYSIS results or intermediate products.
IA will be used to create and update calibration files and to make refinements to SPG algorithms. In most cases these will be fed back into the pipeline. Other products of IA include trend and astronomical data.
IA contains the following subsystems:
By analysing SWS data with an interactive version of the SPG pipeline software enhancements to the pipeline may be possible.
CA is the tool used to fulfill the requirements from the ISO In-Orbit Calibrations Requirements Document (IOCRD), mainly by producing the calibration files. CA will be composed of many modules each of which executes a particular calibration procedure to fulfill a specific IOCRD requirement.
TA will be done e.g. on the diffuse calibrator outputs, detector characteristics etc. to study trends in the instrument behaviour. There is some overlap between TA and CA in that trend analysis will be required for full understanding of the SWS calibration.
Simple data analysis will be possible on the final output of the pipeline to ensure that the observations have achieved their aims.
While monitoring of the instrument is primarily a QLA task, it may also prove necessary to carry out some analysis of SWS OLP results to help pinpoint or resolve instrument problems.
