- Ran preliminary analysis on Double cluster images from observation 2, made HR diagram.
- Magnitude calculated using equation:
Filter |
Flux at m=0 (photons s^-1 m^-2) |
B |
4260*1.51e7/0.22 |
V |
3640*1.51e7/0.16 |
R |
3080*1.51e7/0.23 |
- (Note: flux sometimes measured in units of Jy, 'jansky', where 1Jy=1.51e7 (dLambda/Lambda)^-1. This is shown above. Source:http://www.astro.utoronto.ca/~patton/astro/mags.html)
- For best match to real data, calculated offset c for both B and V filters:
- B: c=-8.14300827674
- V: c=-8.28699220211
- HR diagram (cutoff applied to real data):
