+% function [varargout] = banana_scan(basepath, scan, Nx, Ny)
+%
+% This function only works for mesh scans done to see the undulator banana
+% with spec. This is an example pf such scans:
+% dmesh idgap -0.05 0.05 50 sl1cv -0.4 0.4 8 0.2
+% 50 steps (51 points) along the fast axis
+% 8 steps (9 points) along the slow axis
+%
+%
+% Input parameters:
+%
+% basepath: main path where you are working
+% scan: scan number of spec mesh scan
+% Nx: number of points in fast axis
+% Ny: number of steps in slow axis
+%
+% please reports bugs, problems, suggestions for improvements to:
+% CXS group
+%
+% the case of duplicate scannumbers in the spec file, and how to
+%   address them remains to be implemented
