... The first step to improve the FORS calibration is therefore to obtain data to allow a computation of the illumination correction across the field. ... Another limitation on the calibration accuracy has been the brightness of the Landolt standards which have forced the use of extremely short exposures introducing small but non-negligible shutter-time errors and also resulting in a very small number of useful standards per frame. ...

Next: Reducing the observations Up: PEPSYS general photometry Previous: Influencing the plan . ... If the telescope and instrumentation are unfamiliar to you, you may have trouble keeping to the schedule for the first night or two, so try to work with a previous observer on the equipment for a night or two of training before your observing run. If you fall behind, try to keep as many low-altitude observations of extinction stars as you can, and drop some circumzenithal ones if necessary. ...

... In this lecture, we will introduce addition and multiplication that turn the set of (equivalence classes of) species into a commutative semiring with unity. De nition. Let F and G be two combinatorial species. The sum of species is de ned as follows. ... Each of the three generating series associated with the sum of species is equal to the sum of corresponding series: (F +G)(x) = F (x) +G(x); ( ^ F +G)(x) = ~ F (x) + ~ G(x); Z F+G = Z F + ZG : Examples. ...

. The seminar is supported by the grant of Federal Programm "Integration" . annotation of talk . S.Ibadov (Astrophys. Inst, Tadjikistan) . "Generation of X-ray in Comets" . Generation of X-rays in comets due to production of high-temperature plasma blobs from collisions of cometary and zodiacal dust particles is being considered. Observations of dusty comets in the zone of small heliocentric distances (R<1AU) by the ROSAT and XMM-type X-ray telescopes seem warranted.
