Meinunger (1966) classified it as an eclipsing binary with a period very close to 1 day, noting however that the period and derived minima times were uncertain due to the low variability amplitude. As of July 2011, the O C gateway (Paschke Brat 2006; Paschke 2009) lists, in addition to Meinunger's photographic data, 2 visual and 3 CCD times of minima from Paschke (1988, 1996, 2006), Stepan (1995), Br t et al. ...

In a linear problem, if the errors on the observations have a gaussian distribution, the ``Maximum Likelihood Principle'' gives you the ``best estimate'' of the parameters as the solution of the so-called ``Least Squares Minimization'' that follows: . ... A certain number of numerical methods have been developed to solve the non--linear least squares problem, four have so far been implemented in MIDAS. ...
