Rates Update

→ For the plot below, I assume the following:

→ Total rates have been included, and are shown plotted with the D2 rates

→ Error bars shown are statistical only

→ I found a slight bug from previous calculations: I was assuming the time output was in hours, but it was in fact in days

→ This has now been corrected, but all previous time calculations are under-estimated by a factor of 24

→ F1 and F2 are now calculated using the Bosted fits, which lets us extend into a higher x range

→ It is valid for 0<W<3.2 GeV and 0.2<Q²<5 GeV²

→ The rates note has been updated to fix the sign problems that Oscar and Dustin noted

The max SHMS DAQ rate is 1kHz. The estimates above were done to show what we can do without prescales.
