The magentaVIEW command is a powerful alternative to magentaSHOW, the later being inefficient when the number of spectral line channels is large.
magentaVIEW provides a 4 panel display for 3-D data cubes, with the current channel bitmap, the integrated area bitmap, the current spectrum and the integrated intensity spectrum. The spectra can be displayed with 2 simultaneous frequency windows, a broad and a zoomed one, allowing browsing through a large number of channels. Spectral line identification (from the line catalog specified using command magentaCATALOG) can be added by typing L when the cursor is on one of the 2 broad-band spectra.
magentaVIEW CCT will display the cumulative flux of Clean components
for all channels in just one panel, instead of a per-channel panel
for magentaSHOW CCT
Similarly, magentaVIEW NOISE will plot all pixel intensity distributions
from every plane in a single panel, contrarary to magentaSHOW NOISE.
magentaVIEW /OVERLAY allows to overlay (in contours) the plane
of a second data cube. The main use is to overlay the continuum, or
a plane of the current data cube to help revealing velocity structures.
magentaVIEW will fallback to magentaSHOW whenever it has no specific
support for a given action.
Like magentaSHOW, magentaVIEW /NOPAUSE will not loop
interactively to explore the data cube, but just display the view
with its current parameters (channel, velocity range, support). The same
behaviour can be obtained by setting blueDO_LOOP to NO.
