Error in AntennaAzimuthDirection
Closed this issue · 4 comments
There are errors appearing in the total surface current magnitude calculated for the star pattern tracks on May 22nd. Tracing back there appears to be an error in the calculation of the antenna azimuth, which in turn is producing errors in the currents. For one sample track the Antenna azimuth images are suspect:
Fore-beam:
Aft-beam:
Here the Fore-beam shows antenna azimuths of <0, where they should be modulated to 360 degrees as this is a bearing from North (defined by the Orbit Heading and beam squint). Additionally there are noisy radials that have an unknown provenance
It appears that the means to identify antenna location (i.e. Fore or Aft etc) is faulty - Aft antennas are being identified as Fore and vica versa
Error traced back to identify_antenna_location
For a file that is named as aft (i.e., '77' in the file name) and has a mean SquintImage value of ~ -45 degrees the mean between MinProcessedDoppler and MaxProcessedDoppler is positive, which is supposed to signify a forward pointing antenna.
Suggest changing the means to identify antenna location purely by filename until this can be properly resolved using data within the datasets
