Af(rho) parameter according the CARA-approach

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

Comet C/2014 Q2 (LOVEJOY) -   30 june 2015

Image comet C/2014 Q2 (LOVEJOY) taken from  BRIXIIS Observatory with a 0.4-m f/3.8 telescope and SBIG STL6303E camera. Image below is an average of stack of 15 images of 60 sec with Clear 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 1 x I + 1 x R with exp. Time of 60 sec each in 1x1 Binning

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