Antenna phase center

1

I’m trying to obtain the phase center offset for a third party gps antenna for use with my M2. The model number is Beitian 300S. I attempted to contact the manufacturer without success. I did obtain calibration files from NOAA for this model, but I don’t know how to interpret them. Can anyone assist or send me in the right direction? I have included the calibration files below

It is 61.7 mm for L1 frequency and 51.8 mm for L2 frequency. Practically, you can use the mean, 56.75 mm.
