Import/Export of Source Information

Positions, velocities and the ``expected properties'' of multiple sources can be added to a Science Goal from an ASCII file using ``Load from File...'' located at the bottom of the node. This can be used to either load a set of additional sources, or to completely replace the list of currently-defined sources. The format of the ASCII source list is shown below; it should be possible to cut and paste this into a text editor. Alternatively, the ``Export to File...'' option can be used to create a template.

Name, RA(sex), Dec(sex), PMRA(mas/yr), PMDec(mas/yr), vel(km/s), Ref frame, Doppler type,
peak cont flux(mJy), peak line flux(mJy), cont pol(%), line pol(%), line width(km/s)

In addition, the individual pointings that make up a field definition can also be imported or exported to file, on a source-by-source basis. An example of the format is:
RA , Dec, Coordinate Type, Coordinate Units

 04:31:38.4369, 18:13:57.651,Absolute,Sexagesimal
 04:31:40.5426, 18:13:57.650,Absolute,Sexagesimal
 04:31:36.3312, 18:13:57.650,Absolute,Sexagesimal
The ``Absolute'' coordinate type can be combined with the units ``Sexagesimal'', ``Degrees'' OR ``Radians'', whilst ``Offset'' pointings can be defined in ``Arcsecs'', ``Arcmin'' or ``Degrees''. Both the unit and coordinate type are case-insensitive. It is not possible the read the pointings in for a rectangle.
