This example shows how to define an arbitrary weighting
scheme that is a function of SIGMA, FOBS, FCALC, S, H, K, and L. The
statement should be inserted at any place after reading the
reflections and before calculating the structure factors with the
new weights. The following lines are examples of possible
weighting schemes:
RESOlution 8. 2.5
FWINdow 0.1 100000.
DO (WEIGHT = 1. / SIGMA^2 )
DO (WEIGHT = 1. / ( 10. + 60. * ( S()/2. - 0.16667 ))^2 )
