[Aavso-photometry] Software for combining time series data taken with different filters to calculate transformed magnitudes

[George Silvis]

I have an application that I've made available for applying transform 
coefficients that may be of interest. It is available at 
http://www.gasilvis.net/transformer/ .
This would take as input your untransformed data in AAVSO WebObs 
submission format, and your coefficients, and then would write a new 
WebObs submission file with the transformed data. You can control 
which obs are in each BVI set by using the group field in the 
submission record.

This tool does not do any interpolation as it assumes the different 
obs in the transform group are close enough in time.

If you have any questions, please ask.

Cheers,
George
