SYMMETRIC FUNCTION

Adds a circularly symmetric function to the current data, calculated from a 1-D profile. The 1-D profile needs to have been previously loaded into the memory (the first row in the memory is used to store the 1-D profile). The user specifies the centre of the required function in data coordinates. The function is added to the current data³¹.

(A 1-D radial profile can be calculated within the FIT sub-menu using the POWDER DIFFRACTION command, see Section 17.18, Page .)
