    55.. WG Bouwman, DUT, added during CodeCamp-V in Oct 2016 the SESANS data format

    8283The file format has a list of name-value pairs at the top of the file which detail the general experimental parameters necessary for fitting and analyzing data. This list should contain all the information necessary for the file to be 'portable' between users.

     85Following the header is a 8 (only the first 4 are really needed) column list of instrument experimental variables:

     89- depolarization error in the same unit) (measurement error) 
    8790- Spin echo length error (:math:`\Delta`\ z, in Angstroms) (experimental resolution)

    11 (ie, I(Q) vs Q), one that displays *1D residuals* (ie, the difference between the 
    12 experimental data and the theory at the same Q values), and *2D color maps*.
