% 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
