spurshow

procedure spurshow, [/showcenteradc]

Using the current displayed data container, mark any VEGAS ADC spurs associated with it using vertical lines (vline).

If the vegas spur header parameters are invalid or there are no spurs found within the number of channels present in the data then no vertical lines will be drawn.

All of these vertical lines will have the idstring 'vegas_spur'. They can all be cleared by using clearvlines for that idstring.

Note: Vertical lines are persistent in the GBTIDL plotter. They remain as different data containers are displayed. clearvlines or clear must be used to erase these lines.

This routine always clears all 'vegas_spur' vertical lines before it tries to redraw any at the spur locations.

in, optional
boolean When set, the marked spurs will include the center ADC spur. Normally this is unset and the center ADC spur is not marked. The usual sdfits behavior is to replace the data value at the center ADC spur with the average of the two adjacent channels.
