Next: Radiation Hardness Up: CCD Scientific Performance Previous: Dark current and cooling . The full frame mode of operation is widely used for optical astronomy in order to obtain the greatest focal plane coverage. In X-ray astronomy this mode has a disadvantage in that for the relatively shorter image integrations required to maintain a photon counting mode, smearing of the images occurs during readout when the photons continue to fall on the moving charge pattern. ...

Development of interferometry at Keck Observatory has commenced, with the initial phase to be the combination of the two 10-m telescopes. ... The proposed second phase would add outrigger telescopes to enable synthesis imaging as well as narrow-angle astrometry for an extensive planet search. ...

SUMMARY OF THE RESEARCH PROPOSAL by Maxim Vsemirnov Research topic: Hurwitz and (2,3)-generated matrix groups and related problems. ... The reason to study these groups arises from the fact that the class of (2, 3)-generated groups together with three cyclic groups {1}, C2 and C3 is exactly the class of quotients of the classical modular group PSL2 (Z). ... The answer is known for sporadic groups, some exceptional groups of Lie type and for the most series of classical matrix groups of large rank. ...

This paper comments on classical confidence intervals and upper limits, as the so-called a flip-flopping problem, both of which are related asymptotically (when n is large enough) by the definition but cannot be converted from one to the another by preserving the same coverage due to the poisson nature of the data. ...

... Let us first find out which way -- rise in spectral resolution with some loss in the S/N ratio or increase in the S/N ratio with a fixed spectral resolution -- is better for the purpose of reduction of equivalent width determination errors. ... N -- number of counts for 1 ? ... line equivalent width, . ... Thus if the spectral resolution is managed to be increased (i.e. to decrease )without loss in the number of counts falling at 1 ?, the equivalent width measurement error is then proportional to . ...

... 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. ...

... I do have a problem with the realtime capabilities of Linux. I wrote a loadable driver which uses the RealTimeClock to generate periodic interrupt at a frequency of 1024Hz. With each interrupt the driver increments an internal counter. The 'read' function of the driver returns simply that counter. Next I wrote a realtime task (with the highest priority) which read that RTC continuously. This tasks checks if the read counter is incremented by one between two read calls. ...
