Applycal ndppp_prep_target crash #19

Closed tikk3r closed 5 years ago

tikk3r commented 5 years ago

On the "new" branch. https://github.com/lmorabit/long_baseline_pipeline/blob/7100c23363907dd7e1ee25fca18f811899b4f022/LB-Delay-Calibration.parset#L268-L271

ndppp_prep_target crashes when it tries to apply the RMextract solutions:

std exception detected: SolTab RMextract does not exist in solset combinedsols

For me, either solset_name needs to be target if it should only have it for the Dutch stations, or add_IS_h5parm needs to be run before the RMextract steps (it extracts the present stations by looking at the stations in the existing solset).

lmorabit commented 5 years ago

the solset_name should be combinedsols -- use losoto -i solutions.h5 to check if rotationmeasure000 exists in this solset and let me know if it doesn't.

In the input solutions.h5 (i.e. straight from prefactor) rotationmeasure000 exists in the calibrator solset, but not in target.

lmorabit commented 5 years ago

Then something has gone wrong with the h5imp_RMextract step, which is supposed to add rotationmeasure000 to target. The add_IS_h5parm should copy polalign, clock, and bandpass ONLY from the calibrator, and copy all of the solutions from target (which should include rotationmeasure) -- both of these get copied to the 'combinedsols' solset. Do you have a logfile?

tikk3r commented 5 years ago

Something is weird about this run and must've gone wrong. Running it on another dataset I don't encounter this crash/problem. Closing it for now.
