< < | Using Aladin to find H-R diagram of pleiades |
> > | Observation
Took multiple photos of Pleiades in small field of view in different filters.
Then moved to a wider field of view, no filter. Aiming to use this for HR diagram rather than the smaller field of view:

Star fitting does seem to work even with the estimated values discussed in last meeting, also need to talk about what Gaussian we are fitting. |

> > | Finding Optimum Threshold
Multiplier much higher than expected. Is this something wrong with the simulation or the code? Image used (500 stars):
Star Matching Algorithm
Attempted on real data, haven't actually changed the code yet. But it works for most of the stars using real data:
