... Abstract Compute the geometric position of a target body relative to an observing body. ... Detailed_Output pos contains the position of the target body, relative to the observing body. ... Particulars spkgps_c computes the geometric position, T(t), of the target body and the geometric position, O(t), of the observing body relative to the first common center of motion. Subtracting O(t) from T(t) gives the geometric position of the target body relative to the observer. ... Link to routine source . ...

A typical radio dataset might be a 3-dimensional "cube" named AURORA, with axes RA, DEC and FREQ. ... These can be specified by giving the axis name(s) and grids for each subset. For instance, AURORA specifies the whole 3-dimensional ``cube''; AURORA FREQ 3 specifies the subset FREQ=3 (i.e. the RA-DEC plane at FREQ grid 3) of the set AURORA. ... Specifying only the axis name, and no grids, selects all subsets along that axis: AURORA FREQ selects all RA-DEC planes in AURORA. ... axis centre. ...

makeasn -- Group images in "associations" makeasn *cal.fits . ... The output are calnicb type "associations" tables. These tables contain the names of the images in each group, and the relative offset of the images in pixels. These files can be used to co-add iamges either with calnicb or with asncombine. ... In addtion, the observing time as well as the relative orientation of the imgages can be used as a criterion for an images to be included in a group. ...

Use the LAYER tag to specify an absolute position for a block of content, and use the ILAYER tag to specify a relative position. ... HEIGHT=" height " . ... OnFocus=" JScode " . ... HEIGHT="height" specifies the height of the layer's clipping region and serves as the reference for setting the relative height of children layers. ...

... A document window is shown, with 8 lines (numbered 1 to 8), each 24px high. The text of the "outer" box (at the end of line 1, halfway into line 2, and halfway into line 3) is shifted upward 12px. The text of the "inner" box, thought shifted upward as well, has been relatively positioned so that it lies in its normal flow position at the end of line 2. ... The lines, as they appear in the image, contain: Start 1 Beginning of body contents. 2 of outer contents. Inner contents. ...

The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver or modem. ...

Internet time synchronization: the Network Time Protocol. ... Mills, D.L. Network Time Protocol (Version 3) specification, implementation and analysis. ...

... The HST uses an onboard model of its orbit to perform in real-time various control functions relating to spacecraft operations and observation support. ... New coefficients for the ephemeris are updated every other day, and are archived as FITS keywords for each HST observation data set. Using these coefficients,an observer can perform a variety of calibration and characterization calculations relating to the orbital position and velocity of the telescope. ...

Region markers can be moved, resized, rotated, zoomed, deleted, and can change geometric type. ... For example, markers placed on astronomical catalog positions should be fixed so that one cannot accidentally move them off the specified position. ... Parameters can be fixed using the fix option of the regions public access point (for fixing classes of markers) or by means of a fix keyword in the definition of an externally loaded marker. ... In the command: echo "regions fix all -position -size" | ...
