if we use the above eq. when
m(B-V)= 1.2, T= 3930
when m(B-V)= 1, T= 4420
when m(B-V)= 1.4, T= 3530
so the uncertainty of T= is 4420-3530?
OR
we have to do it separately on both sides?
upper uncertainty= 3920-3530
lower uncertainty= 4420-3920
Thanks
I have a question regarding the results of my Physics investigation on Tc and Teff of stars. I found that the colour temperature that I calculated is significantly higher than the Teff for O and B stars. For mid temp stars, Tc is still more than Teff but the difference in small. But for cooler...

Wait, I'm really sorry, the equation supposed to have minus one after e, that's why i can't solve for T in terms of m(B-V) numerically. sorry again for uploading the wrong eq. thanks for the reply
yes it's easier to measure, but the question is, why does it affect the accuracy of temperature calculated based on the star's U-/B/B-V/V-R?? because we're just going to get either lower or higher values of B-V, V-R, R-I which correspond to temperatures. I mean for cooler stars, we already...

Hi, in determining the temperature of stars using colour index (U-B,B-V,V-R, etc), why do we need to use the appropriate pairs of filters based on their range of temperature? (this is what i read from wiki)
For cool stars, we use R-I, and for hotter stars, we use B-V. I don't understand how...
i have an equation like this:
Given m(B-V)= 1.2 +- 0.2
How do you calculate the uncertainty in T? (btw, I solve T using graphs by finding the intersection point)
My idea was first to calculate T when m(B-V) =0.2, and I then calculate T when m(B-V)= 1.2 + 0.2(its uncertainty). and then find the...
