ALMA Solar Script Generator: First step towards automated and robust processing of solar ALMA science data

After more than three years of development and commissioning Solar ALMA
Observing Mode has been introduced in early 2017 for acquiring science solar
data with the ALMA observatory. The solar observations still work in
so called "non-standard mode" which also means that the data calibration
and interferometric synthesis (imaging) is being done manually - the Data
Analysts at the ALMA Regional Centers (ARCs) or PIs (if they wish and are able
to re-process the data) have to prepare 'ad hoc'
calibration and imaging scripts tailored to a given dataset. This is a big
difference to the standard (non-solar) ALMA observations, where the data undergo
automated and robust pipeline calibration and imaging. However, even for the
non-solar data the pipeline was not always the standard: Their calibration
had started (a few years ago) also as fully manual, later being replaced by an
intermediate semi-automated approach based on the "Script Generator" - a
Python utility that researches inside the ALMA Measurement Set and creates the
tailored calibration and imaging scripts automatically. In order to approach
the Solar ALMA Observing Mode towards the standard calibration pipeline, we
have started developing the Solar Script Generator - the collection of
Python classes and their methods derived from those used in the non-solar Script
Generator that incorporates specifics of the solar calibration and imaging
procedures. In this contribution we shall present the current state and our
vision of solar ALMA science data processing.
