2025 marks thirty years since the first release of WCSLIB, a software library closely linked to FITSWCS, the FITS World Coordinate System standard. From the start, WCSLIB informed the development of FITSWCS and now provides one of several practical implementations. In this talk I will describe WCSLIB's origins, its close connection with FITSWCS, and major milestones in their evolution. I...
As astronomy data sets become larger, efficient data ingestion systems are required to ensure science ready data products are promptly available to the community. Within Data Central’s Ingestion system, bottlenecks were identified with the use of py-spy and diagnostic queries against the ingestion database. Rectifying inefficient database usage resulted in an 8 times speed up of some ingestion...
The SIXTE (SImulation of X-ray TElescopes) software is a general end-to-end simulation toolkit for X-ray observations, covering the full observation process from source photon generation to detector readout and the production of high-level output files. It is the official simulator for existing and future X-ray missions, such as eROSITA, NewAthena, THESEUS and AXIS.
Originally being...
