Dear colleagues,
I am working on the cause of the substantial O-C variations in cataclysmic variables and post-common-envelope binaries. I am sure, you have observations of at least some of the objects, we are following up and I wounder, how I can access such data of yours, which requires to search for an object by name or coordinates.
Currently I am interested in HU Aqr, NN Ser, HW Vir, QS Vir, V470 Cam=HS0705+66, CSS080502, CSS06653, CSS041631 WD1333, . . .
Would your group be able to provide eclipse data (raw light curves or mid eclipse times) on such objects?
Thanks in advance______ Klaus Beuermann
