Abstract

This chapter provides the basis to compute observables for a given set of eclipsing binary parameters and a given set of times or phases. Typical observables are light curves, radial velocity curves, polarization curves, and line profiles. Since in this chapter the focus is on general considerations, no details of implementation are given. Those are found in Chapter 5 for several light curve models.1 Eclipsing binary data analysis leads to a nonlinear least-squares problem in which observed curves are compared with model curves. The presentation is greatly simplified if we take the following formal approach: we formally define an eclipsing binary observable curve, Ο, as a mathematical object
$$ O: = \left\{ {\left( {{t_{k,}}{O_k}} \right)\left| {1 \leqslant k \leqslant n} \right.} \right\} $$
,i. e., as a set of n elements in which each element is a pair, (t, o), where t represents an independent, time-related quantity and o is the corresponding observable. The quantity t used as the independent quantity may either represent:
  • time; or

  • the photometric phase ɸ defined in formula (2.1.1).
