A new road map for the Radio Observatory processing pipelines
| Submitter: | Emanuela Orru |
| Description: | Since May 2018 the Radio Observatory has started a new projected aimed at implementing state of the art calibration processing pipelines on production scales. These pipelines will allow the Radio Observatory to provide science-ready data to the full LOFAR community and external users. A dedicated team of developers, called Team Green, will do this project. The members of this team come partly from the in-kind GLOW contribution (D. Rafferty, A. Drabent and B. Adebhar) and partly from the Radio Observatory (E. Orru and J. Schaap). The project kicked off with a busy week in which the team members followed lectures and demos about the RO development methods and the specification, processing and archiving systems. The scrum methodology has been chosen for use in the project, with sprints of three weeks to build up system functionalities that will allow the RO to run among the most complex LOFAR calibration schemes available. The first milestone is to implement and offer to the users the HBA direction-independent pipeline (pre-factor). This pipeline not only will allow the user to dispose of pre-calibrated data, but, due to the compression, will also aid the data transfer between the LTA sites and the user's computational facilities. Further work will aim toward implementation of new pipelines or new releases of existing pipelines, for instance the new pre-factor pipeline suitable for HBA, LBA and international baselines. Other examples are the direction-dependent pipeline being currently developed by the CITT and polarisation and long-baseline pipelines. |
