M48 HR data linearity

Scatter plot and linear fit of star flux based raw magnitude vs Tycho catalog magnitude based on Messier 48 open cluster image B and G channel data.

 

This data is utilized in my Hertzsprung-Russell diagram of M48.

 

Tycho catalog B and V magnitudes were used, which accounts for small discrepancies since my filters are not photometric.

 

I also wrote a blog posting about the process.
