5.2 Common Imaging Task Parameters

Inside the Toolkit:

The im.setimage method is used to set many of the common image parameters. The im.advise method gives helpful advice for setting up for imaging.

We now describe some parameters are are common to the imaging tasks. These should behave the same way in any imaging task that they are found in. These are in alphabetical order.

ALERT: There are still a subset of data selection parameters used in the imaging tasks: field, spw, timerange. In a later patch, we will use the standard data selection set (§ 2.3).

  5.2.1 Parameter cell
  5.2.2 Parameter field
  5.2.3 Parameter imagename
  5.2.4 Parameter imsize
