The table query language TaQL, developed by Ger van Diepen, can be used for quickly inspecting and modifying casacore tables like Measurement Sets. For example, you can easily flag certain bad solutions, inspect and edit the metadata, subtract two data columns in an MS, or quickly convert between J2000 and ITRF. TaQL can be used from python, C++ or just from the command line.

A much-heard criticism on TaQL is that the language is difficult. That is of course not true, once you have learned it. To make the learning process easier, we developed a tutorial with lots of exercises.

The tutorial is located at taql.astron.nl.

This tutorial runs in a web browser. The backend is based on Jupyter and runs, through tmpnb, in a number of dynamically started Docker containers.
