Reference Star Finder Update
Posted: Thu May 09, 2019 5:35 pm
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:
