DSSSD energy (~10keV/ch) versus DSSSD strip # 
Note some eveidence for non-linearity at low amplitude for p+n strips (128-255) cf. n+n strips
(0-127)

Projection of above showing energy spectrum for one strip. Can observe 478 and 975keV K-lines
and prominent Landau peak near threshold. Threshold estimated at ~80-100keV (slow comparator 0x8).

m(p+n strips) = m(n+n strips) = 1, E(p+n strip)-E(n+n strip) = +/- 100keV

Enegy spectra ADC offset correct, no relative gain adjustment
