Here is a problem espace experts could think about:
For elastic H(e,ep) scattering (from kapton foil; run 1250) espace produces the
histograms below. One can see from th_xq and ph_xq, which are spherical angles
between q and detected p, that we have a systematic shift of ~3 deg either in
spectrometer angle readings, or in espace reconstruction. To correct this problem I would change angle readings for H-arm by ~3 deg.
If someone finds a mistake in my analisys, please don't hassle me (won't help).
