+SESANS Format
+-------------
+
+The current file extension is .ses or .sesans (not case sensitive).
+
+The 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.
+
+Following that is a 6 column list of instrument experimental variables:
+
+- Spin echo length (z, in Angstroms)
+- Spin echo length error (:math:`\Delta` z, in Angstroms) (experimental resolution)
+- neutron wavelength (:math:`\lambda`, in Angstroms) (essential for ToF instruments)
+- neutron wavelength error (:math:`\Delta \lambda`, in Angstroms)
+- Normalized polarization (:math:`P/P_0`, unitless)
+- Normalized polarization error (:math:`\Delta(P/P_0)`, unitless) (measurement error)
