Fits a polynomial baseline of degree 10 or less to the data within the specified ranges. If the fit is successful the data stack is pushed and the fit is written to the X-register; use SUBTRACT-SPECTRUM to see the residuals.
Relevant flags:
N_INTS |
I4 | Number of intervals to use for analysis. |
BLF_INTS |
R4 | Pairs of channels defining spectral intervals to be used for baseline fitting, analysis etc.. |
Examples:
