Projection for direct photon R_pAu
Anticipated sampled luminosities at 200 GeV:
- p+p 100 pb-1
- p+Au 300 nb-1
Direct photon yield in p+Au is assumed as scaled from p+p (with Z=197).

Simple calculation on the energy loss impact on the pointing position
The pointing position change due to the energy loss in the detector material can be calculated as:
delta_d = 0.15 * B * R^2 / pT^2 * delta_pT
