3200e	2777-2810	3710-3749	3820-3909

NB The spreadsheet for these tilted orientations and the tilted 4B runs below is incorrect (wrong, wrong, wrong!). The best check of orientation is the relative (i.e. compared with parallel orientation) clusterSize value, which should increase for any tilt. The orthogonal direction of the tilt can then be inferred from the relative clusterSizeX and clusterSizeY values.

There were various positions quoted for DUTs from twiki, run spreadsheet and email. The table below provides the "best guess" positions used. Positions, relative to the back of the 3rd (mimosa2) reference sensor are given, as well as orientations for each bias.

	DUT0	DUT1
Run 4A	SSC-31	Micron1
positions (cm)	19, 19, 19	13, 13, 13
tilt	0, 0, 0	0, phi=-15^o, eta=15^o

positions (cm)	19, 19, 19	13, 13, 13
tilt	0, 0, phi=-15^o	0, phi=-15^o, 0

Analysis Cuts

Changed:

<

>
> chi² and lv1 cuts are based on maxcellres_DUT_chi2 and maxcellres_DUT_lv1 distributions (where DUT is suitably substituted), respectively.
