... 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. ...

... Charge Coupled Devices (CCD) are currently by far the most widely used type of detector in astronomy. ... After a brief introduction to the VLT Control System, the VLT CCD Detectors Control Software is presented. The VLT Control System is a distributed system consisting of a set of UNIX Workstations, dedicated to high level operations, such as coordination of sub-system activities and interface to the users, and VME-based Local Control Units (LCU), dedicated to the control of sub-systems hardware. ...

... Instruments are more complicated than star catalogs, but a MIDAS table file is still useful for holding the description of an instrument. ... The main sub-table contains information about the passbands used, and the second sub-table describes the detector(s). ... Basic data for an instrument file include the passbands used (and any coding that is used to represent them in the data); the detectors used, and their properties; and general information about temperature control and optical cleanliness. ...
