In this Appendix we will describe the items that can be present in an image dataset. MIRIAD utilities such as itemize, puthd, mathd, copyhd, delhd, and imhead or imlist may be used to browse or modify these `header variables'.
Note that the units used in MIRIAD are not always FITS-like, e.g. frequencies are stored in GHz in MIRIAD , whereas in FITS one finds Hz. For example, MIRIAD keeps velocity in km/s , sky coordinates in radians and frequencies in GHz.
