... HST . ... HST Overview . ... Target Acquisition Reference Information There are limits to the brightest and bluest stars that can be acquired with mirrors N1 and N2 because of the very high fluxes of these objects. ... Once you have predicted an acquisition count rate, you then determine the integration time per dwell point during the target acquisition: STEP-TIME. The goal is to have GHRS see 103 to 104 counts at the peak dwell point of the spiral search for either an acquisition or a peakup. ...

In this gallery are many images of Low Surface Brightness Galaxies which have recently been discovered and analyzed. ... The central surface brightness of this galaxy is 24.28 . Malin 2 This galaxy is another huge disk galaxy with a scale length of 15 kpc and a redshift of 15000 km/a. The high surface brightness knot in one of its spiral arms actually has the same color, luminosity and H-alpha equivalent width as the entire Large Magellanic Cloud . ... Truly it is a Low Surface Brightness Galaxy. ...

Given the viewing direction of the star tracker in terms of Right Ascension and Declination of the boresight + astronomical position angle insbs computes the viewing direction of the instrument specified via the instrument parameter - result is written to stdout in verbose form (default) or as a strbs command line if bstoolsout =true. ...

... For reducing data from ESO instrumentation it is assumed that the FITS headers conform the standards set by the document ``ESO Archive, Data Interface Requirements''. ... As an example, in the ESO case the exposure type is stored in the ESO hierarchical FITS keyword `HIERARCH ESO GEN EXPO TYPE'. ... To fill the CCD keywords with the telescope and instrument setup parameters, like name of the telescope, CCD used, read-out noise, frame size, etc. the command LOAD/CCD can be used. ...

SAOtng supports display of photon event data contained in raw files, similar to its support for FITS Binary Table extensions (e.g., X-ray event lists). ... Because event files do not usually contain enough information to generate an image, we have adopted some conventions for specifying how to interpret the data in these files and for how to bin rows of events into images. To image an event file, it is first of all necessary to define the structure of the events in the event file. ...

... Astronomers and technicians strained to get a good view of the monitor that would soon show them the first picture taken with the newly "fixed" Hubble Space Telescope (HST). ... Tension gave way to cheers and exuberant shouts as the image of a star appeared on the monitor, a star without any of the smeared light astronomers had come to expect from the telescope's flawed main mirror. ... Scientists had already begun work on improved versions of its scientific instruments before HST was even launched....
