Subject:
ENA/KASACR/D1 - Minor data issues
DataStreams:enakasacrvptD1.a1
Description:
The v-channel velocity (uncorrected_mean_doppler_velocity_v) is incorrectly filled with 
NaNs. H-channel is correct. 

The receiver gain (r_calib_receiver_gain_hc and r_calib_receiver_gain_vc) is incorrect. 
This does not affect the data quality. 

The incorrect v-channel calibration constant (r_calib_radar_constant_v) is reported in the 
file. The correct value should be: -23.1151218

Similarly, the reported signal-to-noise ratio (signal_to_noise_ratio_cross_polar_v) is 
calculated using the incorrect v-channel calibration constant, and is biased by a constant 
value of -0.1999974

The reflectivity is calculated with the correct calibration constant and is unaffected.
