Compilation of position angles . ... Search an object in the catalogue of position angles . This catalogue (table a103 in the database) presents the compilation of the position angles for galaxies. The position angle of the major axis is counted in degrees (0 to 180) from the North to the East: PA=0 corresponds to a galaxy whose longest axis is oriented North-South. Galaxies are not pure ellipsoids and therefore the position angles may varies with the considered surface brightness level. ...
