Overview on simulations for LHeC   M.Klein  23.3.2017

-----------------------------------------------------------

Calculations are done of the uncertainties of the NC and CC
inclusive cross sections as can be expected for the LHeC. 
These simulations should be compared with the CDR sets and 
replace those of 2013 after checks.


The following sets are provided:


NC/CC Name             Ee[GeV]  Ep[TeV]  P(e)   Charge  Lum[ab-1]

nominal, high luminosity data, negative polarisation  
NC    datlhec760ncem   60        7       -0.8    -1     1
CC    datlhec760ccem   60        7       -0.8    -1     1

nominal, high luminosity data, opposite polarisation
NC    datlhec760ncep   60        7        0.8    -1    0.3
CC    datlhec760ccep   60        7        0.8    -1    0.3

positron data, unpolarised
NC    datlhec760ncepp  60        7         0    +1     0.1
CC    datlhec760ccepp  60        7         0    +1     0.1

low energy data, unpolarised 
NC    datlhec160ncem   60        1         0    -1     0.1
CC    datlhec160ccem   60        1         0    -1     0.1

each  file has a header which should make the meaning of the numbers clear.
 
In the LHeC Note 2013-002 PHY these simulations are described (for
the LHeC case)

For the present simulation the following cuts were applied:

eta_max=5, .95 < y < 0.001

Error assumptions

energy scales: e: 0.1%,  h=0.5%  
      this is the D/MC scale difference

Radcor 0.3%  Photoproduction at high y: 1%
uncorrelated extra efficiency 0.5%

The luminosity error is kept aside, one may assume 0.5-1%.
