Information Line (Fig. 130):
!
If the spectrum is not calibrated, the centroid channel, FWHM, FW1/xM
(all in channels), gross area, net area, and net-area uncertainty are displayed for the ROI.
!
If the spectrum is calibrated, the centroid channel, FWHM, FW1/xM in channels and calibration units (e.g., energy), library “best match” energy and activity, gross area, net area, and net-area uncertainty are displayed for the ROI.

Above Peak.
If the Detector is acquiring data, the values displayed are continuously updated.
NOTE
If the marker is in an ROI, peak information is displayed whether or not the area is a detectable peak. If no ROI is marked, the peak limits are the same as the limits for the
ROI Insert button on the Status Sidebar. If a peak is detected, its information is displayed (otherwise a “could not fit peak properly” message is displayed).
To close the pop-up box, click it or press <Esc>.
This command is duplicated by the Peak Info command on the right-mouse-button menu and by double-clicking the mouse in the ROI.
