slice - draw an x or y slice of the image

  slice[/qualifiers]

Input of slice limits is done using the mouse (the default) by clicking twice on the left button and then once on the right button, or using the /start_pixel and /end_pixel qualifiers. If the slice is along the x axis the cursor is clicked along the y axis to specify the range of y to be included in the x slice. The middle button can be used to undo the previous click. The middle button ends the selection and the slice is drawn. The default will draw the slice over the image. Use the /nooverlay qualifier to draw the slice outside the image.

slice/xslice

The slice is along x-axis. Click the cursor along the y axis to specify the range of y required

slice/yslice

The slice is along y-axis. Click the cursor along the x axis to specify the range of x required

slice/log

The slice data are plotted in a logarithmic scale.

slice/color=m

The color to be used for the slice plot.

slice/start_pixel

The pixel value defining the beginning of the slice (the default uses the cursor)

slice/end_pixel

The pixel value defining the end of the slice (the default uses the cursor)

slice/noooverlay

Draw the slice outside the image area.

slice/filename

Specify the output filename (to be use together with '/output').

slice/output

Write into a file the pixel number, the count per pixel (using only the not empty pixels in the slice), the total count, and the number of non empty pixels.

slice/previous_frame

Allow to draw more than one result slice in the same plotting frame.

slice/mean

slice/spectrogram

If the image contains a serious of spectra, the '/spectrogram`` qualifier will plot the results of the slice in a separate window.

Examples:

slice/x                         ! do an x slice
 
slice/y/log                     ! slice along y axis with the result plotted
                                ! on a log scale.
 
slice/y/log/start=100/end=200   ! y axis slice with the result plotted on a
                                ! log scale. Slice limits are set to x
                                ! start=100, x end=200.
