| Abstract: |
Nobeyama 45m Radio Telescope (NRO45m) is a large single-dish radio telescope that has been operating for more than 35 years. The data processing pipeline for NRO45m (NRO Pipeline) is developed recently as an extension of the single-dish pipeline for the Atacama Large Millimeter/submillimeter Array (ALMA). The NRO Pipeline is able to process spectral line data taken with the On-The-Fly raster scan. The pipeline calibrates the data, protects spectral line features, subtracts residual spectral baseline component, detects and discards low-quality data, and performs imaging to produce FITS cubes for science targets. The pipeline is written in Python and is built on top of Common Astronomy Software Applications (CASA).
This presentation describes overall summary of the framework of the pipeline, details of the extension from the ALMA pipeline, and products of the NRO Pipeline. As a part of this development project, another application to convert the NRO45m observing data into CASA native data format, MeasuremntSet, is developed as well. The NRO Pipeline, combined with the data conversion application, realizes semi-automated operational workflow from the data acquisition through data processing to the ingestion to the data archive. |
