Dear Colleagues,

In support of the switch to absolute calibrations, the igs05.atx and igs.snx 
files have been revised.

I was provided a new igs05_1400.atx file from Ralf Schmid.  It is available at
ftp://igscb.jpl.nasa.gov/pub/station/general/igs05_1400.atx
and
ftp://igscb.jpl.nasa.gov/pub/station/general/igs05.atx

Summary of the changes in the .atx file:

- z-offset value for PRN31 has to be used for official solutions as soon as
possible
- The values for the LEIAX1202 (found only at BAKO in the IGS network) are 
CHANGED.  Confusion in equipment naming led to the posting of potentially 
incorrect values in previous files.
- Three new calibrations are added: TRM55971.00     SCIT, TRM55971.00     TZGD, 
LEIAX1202GG     NONE, TRM55971.00     NONE

The SINEX template ftp://igscb.jpl.nasa.gov/pub/station/general/igs.snx is also 
updated.  Most of the features are discussed in IGSMail 5443.  Additionally, by 
request, the SATELLITE/ID and SATELLITE/PHASE_CENTER blocks have been added.  As 
before, the igs.snx file will be updated daily with the most recent information 
available for the IGS network.

Best regards,
Angelyn Moore
