The numbers plotted come from the teqc program from UNAVCO, given the input of daily RINEX files. Specifically, they are figures from the SUM line discussed in teqc's qc mode documentation: number of complete observations, RMS MP1 (L1 Multipath) and MP2 (L2 Multipath), and observations per slip (inverted and multiplied by 1000).

Daily number of observations (2012)	Daily number of cycle slips (2012)
Daily RMS due to multipath on L1 (2012)	Daily RMS due to multipath on L2 (2012)
