User-defined Source Coordinates
If the true coordinates of an object are not included in the EPIC source list or
the science proposal, the user can define the coordinates of a new source. For
example, lets say that AB Dor wasn't the target of the proposal.
To define a new source's coordinates:
- 1)
- Double-click on the task rgsproc and confirm you are in
the correct working directory. Next to ``add a source with user-defined position,
rate, etc'' click ``yes''. Immediately below, next to ``label for the user-defined
source'' enter the name of your source, ABDor. Next to ``style for entering
the position of the user-defined source'', enter how the source position is to be
defined; the choices are radec (celestial coordinates) and wrtatt (RGS
angular coordinates). For radec, in the two boxes just below, enter the RA and
declination of the source in decimal degrees; for wrtatt, in the two boxes
below RA and dec, enter the dispersion-direction offset from the pointing axis
and the cross-dispersion-direction offset from the pointing axis, each in arminutes.
For this example, lets use radec and set the RA to 82.185493 and the
declination to -65.449329.
- 2)
- Click ``Run''.
