Read ascii column data and create a single sqw file.
>> write_qspec_to_sqw (dummy, qspec_file, sqw_file, efix, emode, alatt, angdeg,...
u, v, psi, omega, dpsi, gl, gs, grid_size_in, urange_in)
Input:
dummy Dummy sqw object - used only to ensure that this service routine was called
qspec_file Full file name of ascii file containing qx-qy-qz-eps-signal-error column data.
Here qz is the component of momentum along ki (Ang^-1)
qy is component vertically upwards (Ang^-1)
qx defines a hight-hand coordinate frame with qy' and qz'
S signal
ERR standard deviation
sqw_file Full file name of output sqw file
efix Fixed energy (meV) (if elastic data ie. emode=0, the value will be ignored)
emode Direct geometry=1, indirect geometry=2, elastic=0
alatt Lattice parameters (Ang^-1)
angdeg Lattice angles (deg)
u First vector (1x3) defining scattering plane (r.l.u.)
v Second vector (1x3) defining scattering plane (r.l.u.)
psi Angle of u w.r.t. ki (rad)
omega Angle of axis of small goniometer arc w.r.t. notional u
dpsi Correction to psi (rad)
gl Large goniometer arc angle (rad)
gs Small goniometer arc angle (rad)
grid_size_in Scalar or row vector of grid dimensions. Default is [1x1x1x1]
urange_in Range of data grid for output. If not given, then uses smallest hypercuboid
that encloses the whole data range
Output:
grid_size Actual grid size used (size is unity along dimensions
where there is zero range of the data points)
urange Actual range of grid
