The CARMA cookbook outlines various procedures to analyse CARMA data using miriad. Although miriad is a general purpose package for radio interferometers, much like for other instruments like SMA and ATCA, there are CARMA specific programs. There are also some helpful non-miriad tools that you could consider installing.


A postscript draft can be obtained directly from [1]. The author appreciates comments, but it will be useful to remind him which version you are commenting on.

Example scripts

Although the cookbook will have annotated scripts for example cases of CARMA data reduction using MIRIAD, the list below is meant to encourage readers to submit their own.

  • Example 1: example of a strong calibrator observed in wide and narrow mode, in order to calibrate the phase offset between wide and narrow. During the source a weaker calibrator in wide mode is then observed. This procedure works well if we can assume that the phase offset between differenent correlator modes does not depend on time. The cookbook has an elaborate example of a procedure where we do not assume this.
  • Example 2: a full data reduction example for observations of the molecular clouds in the NGC604 region of the Local Group galaxy M33, submitted by Alberto Bolatto ( The script has detailed comments.
