dish.nregion - Function

Set the channel ranges for baseline subtraction.

Synopsis
nregion(...)

Description
This function sets the channel ranges for fitting polynomials in baseline subtraction. It is used by the bshape and baseline functions. It offers a direct (non-interactive) means of setting these ranges. setregion provides an alternative, interactive way of setting these ranges using the mouse cursor. nregion accepts a variable number of arguments. The arguments list the first and last channel of each segment of the range to be used in the polynomial fit. The total number of arguments should thus be a multiple of 2.

Arguments

...		channel numbers to demark a range
		Allowed:	integers

Example

- d.nfit(3);
- d.nregion(10,100,400,512)          # use channels 10-100 and 400-512 for the fit
- d.bshape()
- d.nregion(10,100,120,130,400,512)  # use channels 10-100, 120-130 and 400-512 for the fit
- d.bshape()

Returns
Boolean
