To get a fully-calibrated pulsar observation you need a recent Hydra cal, a calibration file which was obtained on a patch of sky with similar temperature to the pulsar, and of course the pulsar observation. Once you have reduced the Hydra Cals you should then reduce the calibration observation and then the pulsar. Establish the name of the cal file and pulsar observation. ... Reduce the pulsar observation when the cal is finished. ... The pulsar observation is now in standard archive format. ...

. To reduce the size of file use the compress command. For example: compress filename(s) . Each file is replaced by one with the same name and the extension .Z . The amount of compression will vary according to the type of file. Text files can be reduced by as much as 50 to 60%. Use the -v option if you want to see the percentage by which each file is compressed. Examples . Restoring compressed files .
