Near Infrared H and K' surface photometry of the three nearby galaxies NGC 2366, NGC 2403 and NGC 4236, used as local calibrators of the Tully-Fisher relation, was obtained using the 2562 NICMOS3 IR array MAGIC attached to the 2.2 m telescope of Calar Alto. The present measurements are co...
The corresponding true distance moduli for the galaxies NGC 2366, IC 2574 and NGC 4236 are 27.63, 27.8O and 27.36, respectively. They are obtained without accounting for internal light absorption in the galaxies. We expect that the standard deviation of the differential moduli does not exceed ...
