FOC Instrument Handbook Version 6.0 89 9.0 FOC WWW PAGES The FOC team has developed a set of WWW pages to allow greater access to a variety of information regarding the operations, calibrations, and documentation of the FOC. ... Descriptions of calibration files and tables used during the standard `pipeline' calibration of all HST data can be found here. ... The un­smoothed flat fields for the FOC are examples of the types of additional calibration data that is available. ...

XMM-Newton Science Analysis System Page: 1 calview July 2, 2008 Abstract An interactive viewer of the XMM calibration database. 1 Instruments/Modes Instrument Mode all all 2 Use pipeline processing no interactive analysis yes 3 Description The XMM calibration database is comprised of  100 calibration datasets (the current calibration le, or CCF [1]), and a number of calibration algorithms and access functions (the calibration access layer, or cal). ... The former is described in detail in cal. ...

... The SIRTF Science Center is developing two Web-based tools that will be used during operations. One tool is for Quality Analysis. ... The basic design requirements for the QA tool are (1) that it provide an easy way of looking at all the data, observation by observation, and (2) that it provide an easy way to specify status and comments for each observation. ... The data accessed by this tool consists of meta-data in the central database as well as the actual data files in the archive. ...

... Instruments are more complicated than star catalogs, but a MIDAS table file is still useful for holding the description of an instrument. ... The main sub-table contains information about the passbands used, and the second sub-table describes the detector(s). ... Basic data for an instrument file include the passbands used (and any coding that is used to represent them in the data); the detectors used, and their properties; and general information about temperature control and optical cleanliness. ...

... The user database is traditionally contained in the /etc/passwd љ file. Some systems use shadow passwords , and have moved the passwords to /etc/shadow љ . ... However, installing shadow passwords later onto a system that did not support them can be difficult. ... The crack љ program can be used to crack passwords; any password it can find is by definition not a good one. ... The user group database is kept in /etc/group љ ; for systems with shadow passwords, there can be a /etc/shadow.group љ . ...

Courtesy of NASA's National Space Science Data Center . ... Venera 5 was launched from a Tyazheliy Sputnik (69-001C) towards Venus to obtain atmospheric data. The spacecraft was very similar to Venera 4, although it was of a stronger design. When the atmosphere of Venus was approached, a capsule weighing 405 kg and containing scientific instruments was jettisoned from the main spacecraft. During satellite descent towards the surface of Venus, a parachute opened to slow the rate of descent. ...

... The Science Operation Department is composed of Astronomers, Telescope Instruments Operators(TIOs) and Data Handling Administrators(DHAs). ... Astronomers have proposed several methods to quantitatively measure the amount of turbulence above the telescope, which the most common ones is Differential Image Motion Monitor (DIMM). In optical testing, the Hartmann test is the common method to test the quality of optical components. ... Hartmann mask consists of 48 lenses. ...

. The ALFA instrument status window is a small window that presents a summary of the ALFA instrument status. The 'Open ALFA instrument monitor window' button opens the ALFA instrument monitor window which contains all the information that is summarised in the ALFA instrument status window.
