The map p(o) was calculated with coefficients
2F(o) - F(c) and with phase alpha(c). F(o)
are the observed structure factor amplitudes,
F(c) are the amplitudes calculated from the
current model and alpha(c) are the phases
calculated from the current model.
The map p(c) was calculated in program O using
a Gaussian distribution function around the
atoms in the current model.
Map grid points within 1.5 A of the
designated atoms were included in the
calculation.
The map p(o) was calculated with coefficients
F(o) and with phase alpha(c). F(o) are the
observed structure factor amplitudes, and
alpha(c) are the phases calculated from the
current model.
The map p(c) was calculated with coefficients
F(c) and with phases alpha(c). F(c) and
alpha(c) are the structure factor amplitudes
and phases, respectively, calculated from the
current model.
Map grid points within a van der Waals radius
of the designated atoms were included in the
calculation.
