[esa-t474] Some Analysis updates

[Mark Slater]

Dear All,

	Here are some analysis updates for your perusal:

http://pcfj.hep.phy.cam.ac.uk:8080/slater/15

Degradation of the resolution over time using a single set of calibration 
constants

http://pcfj.hep.phy.cam.ac.uk:8080/slater/16

Linking the BPM stations

These are both somewhat preliminary and there are additions/corrections 
due in the next week or so, but comments are still always welcome!

Thanks,

Mark
