strange phase plotting with "plot all stations" #34

Closed rvweeren closed 3 months ago

rvweeren commented 3 months ago

For some reason, when plotting phases for all stations, sometimes, the plotting values go outside the [-pi,pi] range. If I hover with the mouse over the dark-red colored parts it reads values of around (+/-)5-6, getting close to the (+/-)2pi range. So maybe an issue with the modulo? (maybe in combination with the reference station)

To reproduce it you can use /net/rijn8/data2/rvweeren/ELIAS_6arcsectest/h5phaseplotbug.h5 (phase plot, waterfall, plot all stations, direction MODEL_DATA_DD17)

Strangely enough, the issue only shows up in about a third of the directions in this h5, with 30 directions. It only seems to show up with the "plot all stations" ((Maybe it has a relation with https://github.com/tikk3r/lofar-h5plot/issues/26))
