% READ_POSITION_FILE Read positions from a file, the format and header are
|
||
% compatible with multiple interferometer positions and standard deviations
|
||
% as written by Orchestra and the sgalil spec macro.
|
||
%
|
||
% struct_out = read_position_file( posfile )
|
||
% Inputs:
|
||
% **posfile filename with path
|
||
% *returns*
|
||
% ++struct_out is a structure containing fields including the values
|
||
% for header and for each scanning point
|
||
|
||
% 12 June 2013
|
||
% June6 2015 - Changed in order to accept an arbitrary number
|
||
% of values in order to be compatible with 10 columns for flOMNI and 19 for
|
||
% OMNY
|
||
% 15 Apr 2019 - Changed name and generalized description beyond OMNY and
|
||
% Orchestra
