... HST . Using multiple FP-POS positions at new COS Lifetime Location. ... HST Overview . ... To minimize such local degradation at the new COS lifetime position and maximize COS FUV data quality, proposers are strongly encouraged to use all four FP-POS positions (FP-POS=ALL) at any given CENWAVE when planning their observations in Cycle 20 as well. ... STScI will keep monitoring the ongoing and planned usage of the different COS CENWAVE and FP-POS positions at the new COS lifetime position. ...

Next: Catalog Construction Up: Observations and Analysis Previous: Source Detections . ... It was assumed that the highest signal gives the most likely position of the source. ... Comparing the summed map with the maps from the individual energy ranges, the one which produced the smallest error box was chosen to represent the source position, as long as was greater than 4, a level chosen to reflect a reasonable degree of confidence in the detection. ...

Next: Analysis Tools for Nebular Emission Lines . ... Extracting spectra from a large number of NICMOS grism images requires a convenient interactive tool which allows a user to manipulate direct/grism image pairs. ... The direct image is used to locate objects of interest, to find the position of the appropriate spectra in the grism image, to determine the optimal extraction technique to use, and to calibrate the wavelength range of the extracted spectra. ... Figure 1: The NICMOSlook User Interface . ...

XMM-Newton Science Analysis System . ... A different approach is done via the setting withctisrcpos =Y: all event energy corrections do not use the actual RAWY coordinate but the corresponding RAWY location of the source ( SRCPOS ) as determined by the task epframes (either automatically or via setting withsrccoords =Y). ... The task epchain may be used with the setting ccds =4 withctisrcpos =Y to process only the CCD 4 where usually the bright source is located that causes the Out-of-Time events. ...

The GIPSY coordinate system is implemented in terms of a collection of mostly FITS-compatible GDS descriptor items. ... The axis name is uniquely related to the physical coordinates of the pixels along the axis. ... For this position the physical coordinate is precisely defined in CRVAL i , and therefore we call this position the projection centre. ... The GIPSY coordinate system also recognizes secondary axis descriptors, which relate grid positions to a different type of physical units. ...

The reference set used is dome centerline coordinates and units of inches. ... The coordinates of the target are: ALFA4 -246.5803 -0.0677 -393.7084 For reference, the focal point of the optics in the same system is: Nominal focus: -248.145 .0 -389.822 The target was not too far from the nominal focus. ...

fitcircle - find mean position and pole of best-fit great [or small] circle to points on a sphere. fitcircle [ xyfile ] -L norm [ -H [ nrec ] ] [ -S ] [ -V ] [ -: ] [ -bi [ s ][ n ] ] fitcircle reads lon,lat [or lat,lon] values from the first two columns on standard input [or xyfile ]. ... Then two locations are found: the mean of the input positions, and the pole to the great circle which best fits the input positions. ... If no file is specified, fitcircle will read from standard input. ...
