Have transform coefficients been generated for BSM TX2 or can I use the old ones from BSM TX? 

Thanks,

Preliminary BSM TX2 transforms

Rich,

These BSM TX2 preliminary transforms for B,V,I  were calculated from BSM TX2 images of NGC 7790 dated 2022-02-26 02.

I'm using these until the official transforms are released.  Measurements transformed with these coefficients seem to fit nicely into a light curve made mostly from BSM TX measurements.


Color Transform for B-V:      1.063

B Mag Transform for B-V:    -0.021

V Mag Transform for B-V:    -0.080

 

Color Transform for V-I:      0.965

V Mag Transform for V-I:    -0.082

I  Mag Transform for V-I:    -0.046
