Here are the transformation coefficients for BSM_Hamren, using 4 photometric nights with Landolt standards.  Unfortunately, in its Hawaii location, the sky conditions are seldom good enough to acquire standard stars, so this set of data comes from 2013, when BSM_Hamren was located in California.  The OTA, filters and camera are identical, so these should be reasonable estimates for now.

Tb_bv = 0.0193

Tv_bv = 0.0071

Tr_vi = -0.0068

Ti_vi = -0.0323

Tbv = 0.9154

Tvi = 1.0391
