Calibrations with and without the radome will be placed into the ftp://igscb.jpl.nasa.gov/pub/station/general/igs_01.pcv file 2. The calibration including the radome will be put into the ftp://igscb.jpl.nasa.gov/pub/station/general/igs.snx file for this antenna+radome pair Procedure up until now has been to record the presence of, and changes in, radomes in igs.snx, but use only the calibration of the radome-free antenna in both igs_01.pcv and igs.snx. Any comment on this is appreciated at your earliest convenience at igscb@igscb.jpl.nasa.gov. Handling the change to calibrations which include radomes for equipment that already exists in the IGS will be considered separately, since there will be quite a bit of coordination required, in view of the time series already generated.
