RM slide breaks if calibration is not done first #306

Closed mbsherma closed 3 months ago

A "previous stages required" message should be displayed, but instead the screen takes forever to load nothing.

This is likely an issue with the initialization of the RM spectrum or calibrated spectra to all nan at native resolution. You can resolve by simply not plotting if RM synthesis hasn't been run yet.

Resolved in commit https://github.com/dsa110/dsa110-pol/commit/cc41ab34214f6f0db9952941e136ac6d013473c6 ; this was actually due to the ionospheric RM calculation taking too long. I've deferred this to when the user clicks the 'Get RMion' button, but will see if I can speed this up further (seems to be an issue with how the new ion RM module https://github.com/lofar-astron/RMextract queries data. To be safe, plotting of 1D synthesis results is deferred to after RM synthesis has been run, and labels have been added for both 1D and 2D synthesis to prevent confusion.
