XMM-Newton Science Analysis System . ... Counts) for an RGS source, overlaying the source dependent energy and wavelength scales. The data can be represented in original format, or rebinned, to contain a minimum number of counts (specified by the user) per bin. In this case, the counts/channel for each bin are plotted verses the centre of that bin, as a histogram. The error values are plotted in gray and are always the square root of the counts. ... XMM-Newton SOC/SSC -- 2007-07-09 ...

Supported systems include: name description ---- ----------- PHYSICAL pixel coords of original file using LTM/LTV IMAGE pixel coords of current file FK4, B1950 sky coordinate systems FK5, J2000 sky coordinate systems GALACTIC sky coordinate systems ECLIPTIC sky coordinate systems ICRS currently same as J2000 LINEAR linear wcs as defined in file In addition, two mosaic coordinate ...

... Because of the need to schedule observations as efficiently as possible, the order in which exposures are executed may be different from the order in which they appear in the observer's Phase II submission-unless an explicit special requirement dictates otherwise. ... Data files can then be associated with the corresponding exposure line in the Phase II proposal by comparing exposure information in the Phase II proposal with data file header keywords. ... Time_Per_Exposure . ...

. This diagram shows a small table with three transparent cells and illustrates how their final background is determined. The table consists of two rows. Four (labeled) cells lie in the first row, but the second cell spans the first and second row. The first, third, and fourth cells of the second row are "empty". Each non-empty cell has a red background and a double black border. Each empty cell has the table's background color (specified as #ff0) as its own. Return to image.

... Apache HTTP Server Version 2.4 . ... Replaces the original client IP address for the connection with the useragent IP address list presented by a proxies or a load balancer via the request headers. ... The module overrides the client IP address for the connection with the useragent IP address reported in the request header configured with the RemoteIPHeader directive. ... When multiple, comma delimited useragent IP addresses are listed in the header value, they are processed in Right-to-Left order. ...

... The initial descriptions of the FITS format provided a simplified method for describing the physical coordinate values of the image pixels, but deliberately did not specify any of the detailed conventions required to convey the complexities of actual image projections. ... They were CRPIX n for the reference pixel location on pixel axis n , CRVAL n for the coordinate value at that pixel, CDELT n for the increment at that pixel in the coordinate value, and CTYPE n for the type of coordinate. ...

... unpriV - filter to unpack ri data (ao) unpriV [ -b bits ] [ -i numInputFifos ] [ -f fifoToOutput ] [ -d dataFormat ] [- t type] . unpriV is a program to unpack a single channel of RADAR INTERFACE (RI) binary data to the specified output format type. ... The radar interface has 2 channels of 2 digitizers each. ... numFifos 1 or 2 to specify the number of channels in the input data. ... fifoToOutput If the input data has two channels then this specifies which of the two to output (1 or 2). ...
