Y values are brightness from real images taken at each of the focuser positions (i.e. at each X value). The goal is to find the optimal focuser position which maximizes brightness (e.g. the X location at the peak). | |
| Sep 16, 2013 at 17:55 | comment | added | Buck | Thanks for the questions and reformatting. The values at the end are Y values (spaced in X). They are put into the regression to determine the coefficients for: ax + bx^2 + c. Actual X values are -40, -30, -20, -10, 0, 10, 20, 30, 40 respectively (i.e. in order Y values appear). The X values are telescope focuser positions. Peter - I am not sure about DV and IV. If this is not sufficient information, I will look at DV and IV and get back to you. Thanks to everyone! | |
