Purpose
=======
The purpose of the IVS-OHIG (Southern Terrestrial Reference Frame) sessions
is to tie together optimally the sites in the southern hemisphere.
Because these sessions concentrate on the southern sites and do not use
observing time to accurately tie these sites to far northern sites (as
the Global Sessions do) they should yield a very accurate regional TRF
around the South Pole.
Schedule
========
This is a schedule generated with the automatic mode of sked using
the variable scan length with a minimum of 60 seconds. The most recent
and updated source flux models are included. SNR goals are 20/18 at
X-band and 20/18 at S-band for all stations.
The predicted SNRs used include a 30 ps noise contribution added
in quadrature, which is a typical size for the reweight constants
size for the reweight constants required in SOLVE solutions.
This schedule was optimized by different features:
- the covariance analysis during schedule generation considers
the previous 2 hours of observations,
- minor SKED optimization parameters
. maximum number of observations,
were optimized over the best (in a covariance sense) 75% of
the possible observations, this produces a somewhat more even
sky distribution,
- observations were weighted by their expected SNRs,
- 30 ps noise contribution added,
- mimimum time between observations of the same radio source was
set to 20 min
- use of CvgONLY in order to improve the geometry of observation
This schedule was made using 60 sources which helped improve the sky
coverage.
