  An accurate calibration of the luminosity measurement of the 2012
Uranium-Uranium RHIC run at 96 GeV per beam is of the greatest importance in
order to measure the total uranium-uranium cross section with a reasonably
small error bar. During the run, which lasted from April 20th to May 15th 2012,
three vernier scans per experiment were performed. Beam intensities of up to
3.4 10$^{10}$ Uranium ions in one ring were successfully accelerated to flattop
at $\gamma = 103.48$ corresponding to 96 GeV/beam. The desired model $\beta^*$
value was 0.7 m in the two low beta Interaction Points IP6 and IP8. With these
beam parameters interaction rates of up to 15 kHz were achieved. This note
presents the data associated with the vernier scans, and discusses the results
and systematic effects.
