3.5.0

3.5.0

Highlights

Apart from many bug fixes and modernizations, a few new features were introduced:

• TaQL now supports copying columns to new columns (e.g. to make a backup of the FLAG column)
• Non-zero coordinates in JPL frames, e.g. the SUN frame, are now interpreted as an offset in right ascension and declination. Previously, coordinates in a JPL coordinate frame were ignored.
• The Dysco storage manager is now built by default as part of casacore.

• Fix precision in T+dT syntax (#1118)

Measures

Tables

• Cache iteration boundaries while sorting tables (#1106)
• Use RefTable for iteration (#1108)
