Af(rho) parameter according the CARA-approach

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

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

Comet C/2014 Q2 (LOVEJOY) -   2 march 2015

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

Image comet C/2014 Q2 (LOVEJOY) taken from backyard observatory, BRIXIIS Observatory with a 0.4-m f/3.8 telescope and SBIG STL6303 camera with Clear, R-Bessel, I-Bessel and V-Bessel filter. Unfortunately there  was almost full moon. Image below is an average of stack of 30 images of 35 sec. Ecah in 2x2 binning The images with the photometric filter R,I and V-Bessel are in particular for obtaining the Af(rho) parameter according the CARA approach.

Imaging session: 30x30 sec with clear filter in 2x2 binning, 30x60” in 1x1 Binning with CLEAR filter and 2 x I + 2 x R + 2 x V with exp. Time of 60 sec each in 1x1 Binning

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