parametric holo scan of one spectral regions for pshell queue

parameters:

phi_range: (tuple (min, max)) defaults to hard-coded PHI_RANGE
|
|
theta_range: (tuple (min, max)) defaults to hard-coded THETA_RANGE
|
|
steps: (tuple (phi, theta)) defaults to hard-coded STEPS
|
|
|
|
region: (dict)
|
|
optional items can be left unspecified and will default to the indicated values.
|
|
for swept mode, include 'elo', 'ehi', 'estep', 'iter' values, but do not include 'efix'.
|
|
for fixed mode, include 'efix' value, but do not include 'elo', 'ehi', 'estep', 'iter'.
|
|
|
|
'name': user-specific name of the region
|
|
'elo': lower kinetic energy boundary of the spectrum
|
|
'ehi': upper kinetic energy boundary of the spectrum
|
|
'estep': energy step size
|
|
'efix': center kinetic energy in fixed mode
|
|
'epass': pass energy
|
|
'ephot': photon energy (default: unchanged)
|
|
'tstep': dwell time in seconds
|
|
'iter': number of iterations/sweeps (default 1)
|
|
'slit': exit slit (default: unchanged)
