. Next: Auto-baselining Up: Basic Processing Previous: Time average separate scans . To make a baseline fit, you must first create a mask of channels to use in the baseline fit. ASAP> msk = scans.create_mask([100,400],[600,900]) ASAP> scans.poly_baseline(msk, 1) . This will fit a first order polynomial to the selected channels and subtract this polynomial from the full spectra. Subsections . Auto-baselining . Malte Marquarding 2005-11-30

This diagram shows how the 'vertical-align' properties on cells combine to determine the height of the row containing the cells. The diagram also illustrates the meaning of some values of 'vertical-align' that apply to table cells: baseline, top, bottom, and middle. The diagram shows a row of five (labeled) table cells of varying heights and alignments. ... The first cell is aligned with the row baseline and extends to just below the row top. ...

... Also the measured signals are affected by detector transients, altering the final results considerably. We present the design and the main features of a software package, developed in order to support the absolute calibration of the instrument. ... In case the fit is not successful, the average of the last 30% of the data is taken as the final signal. ... The two different symbols represent individual calibrations of the final background signals, using the first or the second FCS-signal. ...
