FINDSLICES

Find time slices that are centred close to a given sky position

Description:

This application lists the time-slices within a given set of time-series files for which the telescope was close to a specified position on the sky. For each such position, the file, time slice index and distance (in arc-seconds) is displayed on the screen.

Each time the telescope scans past the supplied position, a continuous group of time slices will fall within the specified radius of the given position. By default, only the closest time slice within each such group is displayed. This can be changed using parameter CLOSEST.

Parameters:

CLOSEST = _LOGICAL (Read)
If TRUE, then only a single time slice (the closest) is displayed for each pass of the telescope past the specified position. If FALSE, then all time slices within the specified radius of the specified positiopn are displayed. [TRUE]
FRAME = NDF (Read)
The position specified by parameters XPOS and YPOS is assumed to be in the current WCS Frame of the NDF supplied for parameter FRAME. If a null (!) value is supplied for FRAME, the position is assumed to be in the tracking system of the first NDF supplied for parameter IN. [!]
IN = NDF (Read)
Input time-series file(s).
RADIUS = _DOUBLE (Read)
The radius of the search circle, in ars-seconds. [300]
XPOS = LITERAL (Read)
The first axis value at the search position. This should be a formatted value for the first axis of the Frame specified by parameter FRAME.
YPOS = LITERAL (Read)
The second axis value at the search position. This should be a formatted value for the second axis of the Frame specified by parameter FRAME.
