... The OM Tracking History Files give only relative displacements as attitude information, and how this will be translated into absolute RA and Dec is still uncertain. ... It is thought, at the moment, that the AHF may only have a very few number of entries in it, and as such, atthkgen may seem not well suited to such a situation. Note though that it is envisaged that the movement offset threshold at which new AHF entries will be input may be reduced from 2.5 arcsec to 0.5 arcsec. ...

... These experiments followed the movement of the subreflector as the antenna tipped from the zenith to the horizon. We find, relative to a coordinate frame attached to the receiver platform : ffl The axial movement (axial defocussing) is 0.7mm ffl The lateral movement, (in the focal plane, normal to the elevation axis) is 2mm, and no move­ ment parallel to the elevation axis. ffl A rotation of 3 arcminutes about the elevation axis. ... This gave the rotation of the subreflector, shown in figure 3. ...

. You can define a file or directory by its location in relation to your current directory . The pathname is given as / (slash) separated list of the directories on the route to the file (or directory) from your current directory. A .. (dot dot) is used to represent the directory immediately above the current directory. In all shells except the Bourne shell, the ~ (tilde) character can be used as shorthand for the full pathname to your home directory. Examples . Did You Know? .

... AstroAsciiData is a Python module to handle ASCII tables. ... The idea to develop this Python module emerged from the fact that ASCII tables continue to be one of the most popular and widely used data exchange formats in astronomy and probably science in general. ... To load this ASCII table, go into Python, load the AstroAsciiData module and read in the table with: . ... demo = asciidata.open('webexa.txt') . ... Users who only want to work with ASCII tables neeed no further python modules. ...
