Calculation of the number of points in the scan

For wavelength range scans the scheme given in the LWS Observers Manual (section 6.4, page 26) can be followed. For line scans the following equations can be used:

Grating line scans (AOT L02)
The number of points in the scan of each line can be calculated from the number of resolution elements on either side of the line () and the oversampling rate () using:

 

FP line scans (AOT L04)
In this case the number of points in the scan is given by:
