The GIF shows the Proms as we move from the outer K1v (blue) wing, through the K2v then the core at K3 and out into the red wing. (There are some compression artefacts due to the reduction in the file size )
The distance from K1v to K1r is approx 1A
The individual images (unprocessed) show the file name - the end digits are the pixel offset from the CWL (K3)
3 = 0.25A, 7 = 0.55A and 17 = 1.33A
The profile graph shows the overview. Also added the probable FWHM Lunt filter curve for comparison.
The Proms are much more visible in and around K3 and become more difficult out in the wings (K1v17)

Re: Prom visibility across the CaK bandwidth
Hi
Great work there Ken.
When I get my observatory re-built \i would like to do the same.
Cheers. Andrew.

Re: Prom visibility across the CaK bandwidth
Nice work Ken looks like K3 is the best for proms
