Introduction

The observations brought inside after a night at the telescope represent just raw data. A number of steps must be taken to reduce these data to meaningful observations. These steps will include expressing the time of each observation as a standard epoch and reducing the observed magnitudes of the individual components. Consideration will also have to be given to any effects that atmospheric refraction might have on the relative positions of the components. If the observations are to be reduced to some standard epoch then corrections must be made for the effects of precession and proper motion on the position angle.
