The inset in the PSF image (when present) corresponds to the central 41 pixels of the PSF.
When the beam shape is significantly non-Gaussian, the dotted contour of the 50% level
of the PSF image will become distinctly visible apart from the fitted synthesized beam,
which is shown as the solid contour.
The Line-free Moment 0 and Moment 8 images are created from the line-free
(continuum) channels identified in the hif_findcont stage. In the absence of
line contamination these moment images (known as the mom0fc and mom8fc images)
will be noise like. A QA score is generated (in part) from the "mom8fc Peak SNR"
defined as [ mom8fc['max'] - median ] / noise from the continuum channels of
the cube, its value is printed on the mom8fc thumbnail.
The Spectral plot shows the integrated spectrum of the cube, if there is a
clean mask the spectrum is red and is taken from inside the clean mask, if not
the spectrum is blue and is taken from the whole image. The black spectrum
shows the noise level per channel. Additionally, the atmospheric transmission
is shown by a magenta line and the hif_findcont channel ranges by cyan lines.
More details about all these plots can be found in the ALMA Pipeline User Guide.
