... Chapter 3: Fixed and Generic Targets > 3.3 Target Brightness and Bright Object Checking . ... Flux information is required to support bright object (ACS/SBC, COS, FGS, and STIS/MAMA) and persistence (WFC3/IR) checking on the target. All flux information relevant for bright object checking must be provided . ... STIS . ... Measured UV fluxes must be provided for any object within 1 magnitude of the brightness limits; if not previously available, they must be first observed with a safe STIS mode. ...

The VLTI Calibrator Selector Tool is a tool intended to assist in the selection of suitable interferometric calibrators for VLTI observations with MIDI and AMBER. It uses a model of the VLTI and its instruments to assess the fringe visibility, given the observed bandpass, the geometry, spectrum, and coordinates of the target and the time at which the observations are to be made. ... The tool offers an HTML/Java based interface and consists of two pages. ... The quality flag depends on LDD_chi2. ...

... 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. ... The telescope system (MILT) will be remotely operable with an on-site operator's assistance by an astronomer located at one of the ARC member institutions. ... Mean Wind Speed . ... Offsets > 10 deg: 1 arc sec rms max . ... 5 sec max, tracking to tracking . ...

... Within the XMM pipeline it is necessary to make a decision a priori whether a given exposure in an observation should be passed through the normal ``scientific'' pipeline. ... This decision is based solely on information readily available from the ODF (via the OAL), for example instrument mode, filter wheel position (except RGS), exposure duration, etc. ... EPIC MOS or pn exposures which are not in a supported mode (see list below) . ... OM science user defined, EPIC M1 image, EPIC M1 image/fast, . ...

Next: The ESO VLT CCD Detectors Software . ... Up: Instrument-Specific Software . ... The framework for data calibration and analysis of the VLT instrumentation is presented, based on the concepts of a calibration plan, pipeline calibration, quality control, and archiving of calibrated data for a ground-based observatory. ... Quality Control Pipeline provides quality assessment for instrument performance data and observing conditions, and tests the results of the Reduction Pipeline. ...

Next: Echelle Reduction Method Up: No Title Previous: Example . This Chapter provides the basic information necessary to understand the echelle љ package implemented in MIDAS . ... Tutorial examples are available in the system (command TUTORIAL/ECHELLE ) and are also included in the Appendix so that users without previous experience in MIDAS could become familiar with the calibration procedures. ... Reduction steps which are not specific to echelle spectra are described in more detail in Chapter . ...

... They are concerned with Attitude Control System of the spacecraft, satellite visibility from tracking stations, limits on the satellite autonomous operations during the orbit, and needs for auxiliary operations with the spacecraft. ... Among the operational constraints the most important one is the number of programmed slews per orbit, which determines the maximum number of radio sources to be observed during one orbit. ... System temperature (K) . ... Progress of the RadioAstron Project in Pictures...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supe
