Here are the transformation coefficients for SRO35, from the 10 photometric nights in Fall 2010 before we switched over to SRO50. These are using the C14, STL-1001E, and Astrodon interference filters.
Tv = 0.019 +/- 0.005
Tbv = 0.947 +/- 0.008
Tvr = 1.084 +/- 0.009
Tri = 0.999 +/- 0.009
Tvi = 1.043 +/- 0.006
kv = 0.154 +/- 0.028
kbv = 0.127 +/- 0.016
kvr = 0.033 +/- 0.016
kri = 0.046 +/- 0.018
kvi = 0.079 +/- 0.017
