Abstract
A new method for the determination of the extinction in the Galaxy is
proposed. The method uses surface brightnesses of external galaxies in
the B and R-bands. The observational data have been taken from the
ESO-LV galaxy catalog. As a first application of our model we derive the
ratio of R-band to B-band extinction. We introduce two methods for
computing the ratio which give: 0.62+/-0.05 (the first method) and
0.64+/-0.06 (the second method) which is in agreement with the recent
literature value of 0.61. This agreement confirms the validity and
efficiency of our model and is an independent verification for the
standard value of the "total to selective extinction". The method of
extinction determination introduced in this paper will be explored in
subsequent publication.
