Neue Elemente fur DM Cygni.
ACHTERBERG H. and HUSAR D.
Abstract (from CDS):
For the RR Lyrae star DM Cyg the elements of a quadratic ehemeris formula are given with that the times of maxima ca be calculated in the whole observation period from 1900 to 2001 in a satisfactory manner. It is shown how to derive from this quadratic formula for any desired reference epoch a linear formula which is of course valid only in a limited space of time. In an example the elements for the linear formula are given for the reference epoch 2452487.371.
