== girders in the model ==

In the real machine, quadrupoles are arranged on girders  (With a few exceptions) featuring a specific  layout of diagnostics and correctors. <br> 
There is a finite number of girder types. We discussed whether one should capture this in the model. <br> 
The first step would be to write scripts to check that the element placement is indeed accurately captured.

== diagnostic and corrector lengths ==

Currently we captured the diagnostics and correctors as zero length elements. <br>
For correctors, this location in the center of it, for the bpms, the location in that of the antennas (3 inches from end of can). <br>
There are benefits to actually model the true length of all of these elements. This is a significant undertaking and likely will have to be done<br>
via scripting to post process the existing decks. It was felt that while it is useful, it is a medium to long term project.

== dipole and quads lengths ==
We have a few locations in the machine for which the dipole elements have an erroneous length.<br>
i.e one should capture the trajectory length which itself is derived from steel length plus extra fringe field length obtained from HGAP.<br>
One needs to review the model to adjust it wherever we have a deviation.<br>. Quadrupoles also need to be reviewed. The focal lengths and placement is accurate, however one might want to adjust slightly their total length (and
therefore their setpoints ) to capture the fringe fields.
