bottom of the Data Window you will see up to three tabs, labeled Sig (Signal), Bg
(Background), and Ref (Reference) which (where appropriate) identify data
acquired via the functions Take Signal, Take Background, and Take
Reference respectively. Click on the appropriate tab to display the trace you
require.
In descriptions of the Data Window and in on-screen captions the terms x-, y-, and
data-axis are used as follows:-
• The x- and y-axes define a pixel's position on the two-dimensional CCD-chip.
• The x-axis (or horizontal display axis) corresponds to the breadth of the CCD-
chip, and may be calibrated in pixels or in a unit of your choice.
• The y-axis corresponds to the height of the CCD-chip and is calibrated in pixels.
No y-axis is shown in 2D Display Mode. In 3D Display Mode, the y-axis is
shown as a diagonal, to lend perspective to the display. In Image Display
Mode, the y-axis is the vertical display axis.
•
The data-axis is calibrated in the unit of your choice and has data values plotted
against it - see SECTION 4.6 CHOOSING THE DATA TYPE. In 2D and 3D
displays the data-axis is the vertical display axis. In Image Display Mode, data
are represented by a color or a grayscale tone.
In all display modes, x- and data-values are displayed on the status bar along the
bottom edge of the Data Window. When data have been acquired in a mode other
than Full Vertical Binning, y-values are also displayed in the status bar.
For a description of acquisition modes, see SECTION 4.5 SETTING THE
ACQUISITION - Readout Modes.
