Reference Star Finder Update

Post by Francois Teyssier »

The Reference Star Finder Spreadsheet is updated:
- correction of an error in the computation of the trajectory of the reference (thanks to Bertrand Guegan)
- add a new feature: visualisation of the error on the computation of the continuum (one can choose among 3 stellar types A G M)

Download: http://www.astronomie-amateur.fr/Docume ... inder.xlsm

In this example, HD107348 (B8V) has been chosen as reference.
If one use this reference to compute the IR response for an hypothetical A0V target located RA 12 h and Dec -15 °(blue curve), the result appears in red

Wrong choice!

Try HD103362

Good Choice !

Note: you can change the AOD and altitude for the computation
The computation uses the model explained by Christian Buil in:

Thank you very much François for these new features !
The new graphs are really a great help to choose the reference star !
