 Interactive jupyter notebook widget to calculate transmission zone plate grating (TZPG, also known as beam splitting off-axis zone plate) beam sizes and position at the sample and detector planes for the SCS instrument.
 
-![TZPGcalc widget](doc/source/TZPGcalc.png "TZPGcalc widget")
-
-The so far implemented features are:
-*  calculates geometric beam propagation for diffracted beams by the grating (1st, -1st and 0th order)
-*  calculates geometric beam propagation for focused and unfocused beams by the off-axis zone plate (1st, 0th order)
-*  calculates beam sizes and position for 2 energies
-*  calculates sample position (membrane size and pitch) as well as etched facets
-*  calculates position of the DSSC module 15 as well as filter bar position
-*  calculates focal length change due to the KBS
-*  calculates beam focusing by KBS for the zone plate 0th order
-*  calculates beam and sample shape for sample at non-normal incidence angle
