8. Selection/settings of geophysical models
If detailed information on geophysical models and a priori interpolation schemes 
is given in separate comment section, options are:
a) use database settings
b) replace database settings (state which?)
c) other (please state details)
If no further information on geophysical models is given elsewhere, 
please describe all models here.

8.1 A priori Earth orientation:
- A priori precession/nutation model: (e.g. IAU2000A  precession-nutation, 
  IAU2006 precession model)
- A priori short-period tidal variations in X, Y and UT1: 
  (e.g. IERS Conventions 20xx)

8.2 A priori geophysical models:
-  Solid Earth tide: (e.g. IERS Conventions 20xx)
-  Ocean loading: 
-  Pole tide: (e.g. Mean pole coordinates according to  IERS Conventions 20xx
- Atmospheric loading:
- Antenna thermal deformation: (e.g. IVS antenna thermal expansion model of 
  Nothnagel (2008) using daily mean temperatures)
- Axis offsets: (e.g. Taken from the IVS Analysis Coordinator's file antenna-info.txt)

9. Parameterization
N.B.: Pre-reduced datum-free normal equations are only interim products, not 
solutions as such. For analyses of the IVS, it is mandatory that these normal 
equations contain coefficients for all site positions' X,Y,Z components and all 
EOP components (Xp, Yp, dXp/dt, dYp/dt, UT1-TAI, LOD (dUT1-TAI/dt), dX, dY, 
(dX/dt, dY/dt optional but desirable for the combination with GPS) and all 
source positions in RA and DEC. Pre-reduced parameters should be described below.

9.1 Clocks
Options:
a) use database settings
b) other (please state details)

9.2 Atmospheres
Options:
a) use database settings
b) other (please state details)

9.3 Other parameters
please state details

10. Outlier elimination
Options:
a) use database settings
b) re-activate all flagged observations and re-identify outliers 
   (please state detailed procedure)
c) other (please state details)

11. Handling of source positions if not yet in normal equations
Options:
a) fix all positions to their a prioris (state which a prioris)
b) Select individual sources to be estimated for this session (please state details)
c) other (please state details)

12. Generation of pre-reduced datum-free normal equations
Options:
a) Unknown - Using standard Solve routines.
b) Program is based on authentic classical least squares adjustment and matrix 
elements of interest are squeezed out by inversion steps. (please state how the 
square sum of residuals is computed).
c) other (Please state original estimation process and procedure to generate and 
extract pre-reduced normal equations. Please also state how the square sum of 
residuals is computed).

13. Further details
e.g. if EOP are estimated and reported in SINEX file --> Datum constraints 
(NNR/NNT conditions on stations, or NNR on sources)
