    33.. This is a port of the original SasView html help file to ReSTructured text 
    44.. by S King, ISIS, during SasView CodeCamp-III in Feb 2015. 
     5.. WG Bouwman, DUT, added during CodeCamp-V in Oct 2016 the SESANS data format 
    56 
    67.. _Formats: 
     
    910============ 
    1011 
    11 SasView reads several different 1D (I(Q) vs Q) and 2D (I(Qx,Qy) vs (Qx,Qy)) 
     12SasView reads several different 1D (I(Q) vs Q), 2D SANS(I(Qx,Qy) vs (Qx,Qy)) 
     13and SESANS (P(z) vs z) 
    1214data files. But please note that SasView does not at present load data where 
    1315the Q and I(Q) data are in separate files. 
    1416 
    15 1D Formats 
    16 ---------- 
     171D Formats SANS 
     18--------------- 
    1719 
    1820SasView will read files with 2 to 4 columns of numbers in the following order:

     51--------------- 
    5052 
    5153SasView will only read files in the NIST 2D format with the extensions

     64SESANS Format 
     65------------- 
     66 
     67The current file extension is .ses or .sesans (not case sensitive). 
     68 
     69The file format is to have a list of name-value pairs as a header at the top of the file, detailing general experimental parameters necessary for fitting and analyzing data. This list should contain all information necessary for the file to be 'portable' between users. 
     70 
     71Following that is a 6 column list of instrument experimental variables: 
     72 
     73- Spin echo length (z, in Angstroms) 
     74- Spin echo length error (:math:`\Delta` z, in Angstroms) (experimental resolution) 
     75- neutron wavelength (:math:`\lambda`, in Angstroms) (essential for ToF instruments) 
     76- neutron wavelength error (:math:`\Delta \lambda`, in Angstroms) 
     77- Normalized polarization (:math:`P/P_0`, unitless) 
     78- Normalized polarization error (:math:`\Delta(P/P_0)`, unitless) (measurement error)
