Af(rho) parameter according the CARA-approach

Af(rho) versus aperture radius (in km) - R-Bessel filter

Comet C/2014 Q2 (LOVEJOY) -   27 apr. 2015

Image comet C/2014 Q2 (LOVEJOY) taken from  BRIXIIS Observatory with a 0.4 f/3.8 telescope and STL6303Ecamera. Image below is an average of stack of 15 images of 75 sec with Luminance filter. Each in 1x1 binning The images with the photometric filter R,I are in particular for obtaining the Af(rho) parameter according the CARA approach.

Imaging session: 1x60 sec with clear filter in 1x1 binning, and 2 x I + 2 x R + 2 x V-filterwith exp. Time of 120 sec each in 1x1 Binning

Results of the Af(rho) parameter can you find below in this page
