Calibration Checking Function

[Jan-Willem]

After the holography data has been extracted it would be useful to have a function that will extract the beam peaks (l=0,m=0) and do a couple of plots.

Data in holog_zarr is organized as follows: [ddi_i] [map_j] [ant_k] [time,chan,pol]

An example is given in the attached notebook: alma_debug_example.ipynb.zip

Aside from naming convention in the private function : ) this is can be checked out now. If it looks good, I'll boring-ify the private functions and we can merge it. Below is a snapshot of what to expect. There are two plotting options, matplotlib and plotly, the later is interactive. I chose let the user specify the polarization because default plotting ever combination looked messy and if desired the user can just do it themselves with a quick loop. @Jan-Willem @vsmagalhaes

Some comments:

• [x] As shown in the example notebook:
  • [x] The option should be given to plot Amplitude & Phase or Real & Imag with the default being Amplitude & Phase.
  • [x] Each figure should consist of 4 plots.
  • [x] Parallel hands should be plotted together: ALMA:(RR,LL) or VLA:(XX,YY). The user should not have to specify this. The pol coord should have this information.
  • [x] Amplitude & Phase or Real & Imag
• [x] It should have a similar interface to plot_antenna:
  • [x] Accept the holog.zarr file name
  • [x] Generate and save all plots (except if the user gives a sub-selection of antennas and ddis).
  • [x] The plots should be saved into a single folder and use a similar naming convention to plot_antenna.
  • [x] If the date is repeated it should be removed from the labels.
  • [x] The plots should have titles.
  • [x] Rename the function to plot_holog_diagnostics

This is done and merged. Not sure why it still shows up.
