plot2 module <baseline>

This module allows baseline correction of the (1-dimensional) slice which has been selected.

{no baseline : automatic : hand-picked} <baseline_used>
This determines whether there is baseline correction, and if so, whether or not the program automatically determines the baseline points or the user does. The display is automatically updated.

{baseline file} <baseline_file>
If the baseline points are 'hand-picked' then they can be loaded from or saved to a file. Alternatively, baseline points may be added by holding the shift key down and clicking the left mouse button at the (new) desired point in the slice display. And baseline points may be deleted by holding the shift key down and clicking the right mouse button near the (no longer) desired baseline point in the slice display (the nearest baseline point is deleted).

{constant : polynomial : trigonometric} <base_fit_used>
The baseline fitting routine can be either a constant, a polynomial or a trigonometric fit. The display is automatically updated.

{half width} <half_width>
If the program automatically determines the baseline points then a 'half width' needs to be defined. This 'half width' must be >= 1.

{next} <next_half_width>
This increases the 'half width' by 1. The display is automatically updated.

{previous} <previous_half_width>
This decreases the 'half width' by 1. The display is automatically updated.

{degree/order} <degree_order>
For polynomial fitting the degree of the polynomial used to do the fitting must be defined. The degree must be between 0 and 3 inclusive. A degree of 0 is the same as doing a constant fitting. For trigonometric fitting the order of the trigonometric functions used to do the fitting must be defined. The order must be between 0 and 3 inclusive. An order of 0 is the same as doing a constant fitting.

{next} <next_degree_order>
This increases the 'degree/order' by 1. The display is automatically updated.

{previous} <previous_degree_order>
This decreases the 'degree/order' by 1. The display is automatically updated.

{load} <load>
Load the baseline points from the specified file.

{save} <save>
Save the baseline points to the specified file.

{clear} <clear>
Clear the selected baseline points.

{apply} <apply>
Update the baseline parameters and display the result.

{dismiss}
Close the module (the parameters are remembered).

{help}
