... To help you get the necessary calibration data in the least observing time, the planning program generates a schedule of required observations. A considerable amount of photometric expertise is built into this program, so that observers without much photometric experience can confidently adopt its recommended defaults, and obtain a plan that should be satisfactory for most photometric observing programs. ...

. The seminar is supported by the grant of Federal Programm "Integration" . annotation of talk . S.N.Fabrika (SAO) . Magnetic fields and rotational periods of white dwarfs . Modern observing data on magnetic fields and rotational periods of single white dwarfs are reviewed. The data obtained with 6-m telescope are also discussed. It is shown in spite of considerable scatter in observed values the magnetic fields and rotational periods of white dwarfs are related as it may follow from the theory.
