... This task performs adaptive smoothing of FITS images. ... Although the task was designed with EPIC X-ray images in mind, it makes few requirements of the input files and can be used to smooth any FITS image in the appropriate data format (see section 6 ). ... The value of can either be kept constant over the extent of the image to produce uniform, non-adaptive smoothing (parameter smoothtype = `simple') or can be made different at different parts of the image ( smoothtype = `adaptive'). ...

... The analysis and reduction of the STIS flanking fields proceeded in similar fashion as for the imaging of the Main STIS Field. ... The DARK calibration reference file used in the CALSTIS data reduction steps was constructed using a 'delta-dark' image appropriate for the epoch of the flanking field observations. ... DRIZZLE drop-size used for the flanking fields was a "pixfrac" of 0.8. ... For information on the data reduction, please read first the technical information for the Main WFPC2 Field . ...

This diagram shows the six superimposed "layers" of the CSS table model. This diagram illustrates the algorithm for calculating a cell's final background. ... The diagram shows how, looking down on the six rectangles, one may compute the background color of each cell. ... A cell without a background color in the top layer is depicted as a "window" onto the lower layers, which give its final background color. ...

In April, 2003 telescope was equipped with a larger-size CCD Andor DW436 . ... 2048 x 2048 pixels, . ... Since summer of 2002 the main focal detector of the RTT150 telescope was AP47p CCD in 1:7.7 Cassegrain focus. ... During September 3-13, 2002 works on installation of new autoguiding system ( photo 1 ) were carried out on RTT150 telescope. ...

Next: Summary of reduction Up: Echelle Reduction Previous: Saving the Data . In the present version we will be concerned with the standard configuration of CASPEC, the Cassegrain Echelle Spectrograph which is in operation at the Cassegrain focus of the ESO 3.6 m telescope. ... In its standard configuration CASPEC uses a a 31.6 lines/mm echelle grating together with a 300 lines/mm grating cross disperser. ... The table shows the change in resolution with the order number.

... Microlocal Analysis is a theory of Pseudo-Differential Operators and Fourier Integral Operators (PDOs and FIOs). ... Microlocal analysis comes in few flavors. ... We will consider semi-classical PDOs and FIOs: one can always get from there to standard PDOs and FIOs but semi-classical theory has more applications. Less formal description of (semi-classical) microlocal analysis is ``a semi-classical limit of quantum mechanics'' or ``high-frequency limit of electrodynamics'' (etc). ...

... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...

... Description . ... The SCORPIO-2 project: . ... The multi-mode spectrograph SCORPIO-2 was developed using the experience of observations at the 6-m telescope BTA with the SCORPIO focal reducer . ... The focal reducer consists of several units ('floors') mounted in the common case in the following order (from the telescope focal plane): . ... The focal reducer is connected with the platform-adapter which used for guiding by offset stars and for illumination the spectrograph by calibration lamps. ...

... This is possible at modest cost due to the low moments of inertia of the telescope and enclosure. ... This same performance will be achieved in higher winds when the telescope enclosure is facing away from the wind, or by using wind screens. ...
