File

**save 2D spectrum**- stores the 2D spectrum and corresponding metadata, for details see section Format of a 2D-COS result file (Matlab)**clear**- data are deleted from memory and figures are set back to their initial state**quit**- exit the program

Load data

**Matlab imaging forma**t: see Import data in the imaging format (Matlab)**Matlab trace format**: see Import data in the trace format (Matlab)

Action

**plot 2D spectrum**: computes the 2D correlation spectrum using the actual settings of the 2D-COS control window**extrema of 2D fcn (function)**: obtains the minimum and maximum intensities of the current 2D correlation spectrum**plot x-slice**: plots a 1D correlation (x) slices at a fixed y-position using the setting from the edit field*[x,y] slice coordinates*(y) of the 2D-COS control window, see screenshot below**plot y-slice**: plots a 1D correlation (y) slices at a fixed x-position using the setting from the edit field*[x,y] slice coordinates*(x) of the 2D-COS control window, see screenshot below**plot [x,y] spectral features**: creates an [x,y] feature plot using the settings from the edit fields*[x,y] slice coordinates*of the 2D-COS control window, see screenshot below**invert colormap**: inverts the colormap**capture to bitmap**: the current color representation of the 2D correlation spectrum is stored in a standard bitmap format**display 2D-COS intensity (on/off)**: chose*on*to enables the*MouseOver*functionality; the option is helpful to obtain the intensity of the 2D correlation spectrum at defined [x,y] positions

## Context Menu

**plot x-slice**: plots a 1D correlation (x) slices at a fixed y-position using the setting from the edit field*[x,y] slice coordinates*(y) of the 2D-COS control window, see screenshot below**plot y-slice**: plots a 1D correlation (y) slices at a fixed x-position using the setting from the edit field*[x,y] slice coordinates*(x) of the 2D-COS control window, see screenshot below**plot [x,y] spectral features**: creates an [x,y] feature plot using the settings from the edit fields*[x,y] slice coordinates*of the 2D-COS control window, see screenshot below
