GEO600 Theoretical Noise Budget - changelog
J.R. Smith 

Version 4.0:
============
02.05.06
- All shot noise curves updated for the best current model of shot noise
given the known paramters of GEO600.
- Detunings of 1000, 550, 350, and 250Hz considered for theoretical noise
models.
- All new theoretical files given v4 markers.

Version 3.0:
============
26.03.05
- All shot noise curves made a factor sqrt(2) higher to correct for a 
overestimate due to the implementation of the mixer in Finesse.
- All shot noise curves made an additional factor sqrt(3/2) higher to
account for additional noise added in the heterodyne process, see Meers
& Strain 1991 PRA vol 44 num 7 pp 4693-4703. The current estimate is now
slightly on the pessimistic side.
- Shot noise and total noise for 350Hz signal detuning added.
- All files given a "_v3" marker in filename. All figures have "V3" patch.

Version 2.0:
=============

16.06.05
- All shot noise curves changed back to the pre-version-control values (so 
factor 2 lower than version1), and other curves changed accordingly.


Version 1.0:
=============

23.03.05 
- Implemented a version control on the noise curves, with 
the most up-to-date curves being Version 1.0. All previous curves 
are considered to be pre-version-control. 
- A version tag appears on all figure formats, as well as in the 
header of each ascii file. 
- This changelog was created to record the history of changes made 
to the theoretical noise curves.

22.03.05 
- All shot noise curves were made precisely a factor of 
two higher than in the previous version. This corrects for a 
misinterpretation of the FINESSE simulation output that was made 
when calculating the shot noise curves. 
- The total noise curves and all figures were also updated to reflect
these changes.
- The signal-recycling cavity detuning frequency is now given in the
legend for the appropriate shot noise curves in all figures.
