This panel adds a pointing error measuring (and possibly correcting) sequence to your slew. ... Log Error measure the pointing error and log it to the current pointing error file (which must already have been opened with the TCC command PTERR OPEN=filename ; this command is not presently supported by TUI, but you can enter manually at the log window; be sure to also issue PTERR CLOSE when you are done logging data). ...

130705 ephemeris tracking . The pnt command has been added to the aotcl interpreter in vxWorks (used for online datataking). within the online tcl interpreter pnt ? ... Load ephemeris file with pnt ephm ld . Track the ephemeris file . Ephemeris tracking was added to the pnt command on 05jul13. ... The new command includes loading an ephemeris file and then tracking using this file. ... The user then starts the ephemeris tracking by issuing the pnt track command: . ... cR current ra,dec . ...

... We now describe the input parameters to the self-calibration tasks. ... For selfcal , you need not perform source , dra , or ddec selection if you use the selradec option (see below). minants : The minimum number of antenna that must be present before the tasks will attempt to find a solution. ... and phase : This determines whether the self-calibration tasks solve for just phase ( options=phase , which is the default) or amplitude and phase solution ( options=amplitude ). mfs : . ...

... It interpolates the grid at the positions in the table and writes out the table with the interpolated values added as a new column. A bicubic [Default] or bilinear [ -Q ] interpolation is used, requiring boundary conditions at the limits of the region (see -L flag option). xyfile This is an ASCII [or binary, see -b ] file where the first 2 columns hold the (x,y) positions where the user wants to sample the 2-D data set. ... Default is 2 input columns]. -bo Selects binary output. ...

... HST Phase II Proposal Instructions for Cycle 20 > Chapter 12: Cosmic OriginsSpectrograph (COS) > ACQUISITION MODES > 12.4 Mode = ACQ/PEAKDConfig = COS/FUV . 12.4 Mode = ACQ/PEAKD . Config = COS/FUV . ACQ/PEAKD Mode invokes a procedure in the COS onboard flight software that takes a series of exposures at different HST pointings offset in the dispersion direction, and HST is repositioned to maximize (peak up) the light intensity through the COS aperture. ... 12.4.1 Aperture or FOV . ...

October 14, 2010 =============== Address BUGS In bisque/mks: add Home on startup -- currently must be homed with the joystick reverse tracking direction in southern hemisphere check southern hemisphere mappings In order of priority -- Make a guide and manual available. Provide a method of determining best pointing correction parameters. ... Fully test pointing corrections on a system capable of arc second accuracy. ...

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...

... Clicking on PLOT S CREEN will display the plot. At this stage, you can fit functions to the data ( FIT : the residuals are plotted and can be manually edited), enter a new plot range (R ANGE : enter 0,0 for automatic scaling) or by defining a window (W INDOW : click left button to anchor upper left corner, click middle button fix size and shift box, click left button again to fix position or right button to select automatic scaling and exit), identify ...

... On-line calibration consists of calibration operations performed to maintain the ALMA observing system properly tuned to successfully execute the planned observations. ... Among processing operations are the calibration of the atmospheric absorption, of phase radiometric correction, of pointing scans, of phase and amplitude reference measurements, .. ... In the mean time tests of the calibration software will proceed using both simulated data and data from the antenna prototypes...?re 1 . ...

... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...
