... The wavelength range covered by the observations was 3200-8040 A. This was divided into three sections, to allow for filter changes, as shown in table 3.1. In each case, the step wavelength between successive ... See full document

... The maxima of the line-of-sight distance distributions in the Galactic plane occur at distances somewhat further than the maxima of the line-of-sight density distributions, due to the volume effect in the star counts. ... See full document

... Using the standard star measurements, it was possible to correct for occasional night to night drifts in the transmission characteristics of the 15 2. filter. These variations occurred only a few times in the course of ... See full document
