... There are compelling reasons for the pulsar community to utilise a standard data storage format. For example, standardisation of file formats significantly decreases the amount of effort required to integrate new instruments into the analysis chain. ... Accordingly, we have defined PSRFITS as a standard FITS-based format for pulsar data files. ... For example, the first line of Processing History HDU contains information about the data acquisition program and the initial structure of the file. ...

... As stable VLT work horses during the past 8 years obviously the two FORSes have in many ways also been instrumental to the definition of the VLT queue observing paradigm which includes both systematic collection of calibration data, online and offline reduction pipelines. The original concept for the photometric calibration and the FORS imaging pipelines involved acquisition of simple twilight images which were used for flatfielding, and observation of Landolt photometric standards. ...
