Previous: How to control imager:
imager reads and writes AIPS++ MeasurementSets and Images. The
format of images is 4 dimensional, with the first two being right
ascension and declination, the third being polarization and the fourth
being frequency. By suitable choice of the input parameters, one can
make images of I alone, I, V or I, Q, U, V for one or all channels.
The makeimage tool function can also make a complex image
of the original polarizations e.g. RR, RL, LR, LL. This latter
type of image is useful for diagnostic purposes.
Images generated by imager may be viewed using
viewer tool or retrieved using the
images tool, the MeasurementSets may be accessed
using the ms tool. More on this in the example below.
