General Description

K band MR spectroscopy of 3 cataclysmic variables (CVs).
2 different sets per target with central wavelengths 2.25 and 2.35, respectively.
Please note: CVs show irregular brightness variations with up to 5-6 mag amplitude
that are caused by a brightening of the accretion disc. Our project aims at
investigating the late-type secondary star in these systems, which, even in the
 K band,
will probably be swamped by an accretion disc in outburst. Therefore, if the target
appears significantly brighter compared to the finding chart, we would very much
appreciate if the respective observation could be done at a later time (1 or 2 weeks;
within the range of feasibility, of course). Thanks in advance ;-)
