Common
The additional analysis function are passed to the cube workflow by adding a det_proc keys to the detector definition dictionary. The content of this key must be another dictionary with the following sctructure:
{
name: '<function_name>' # must be the exact DetObjectFunc name,
'func_kwargs1': <...>,
'func_kwargs2': <...>,
...
}
The function <function_name> will then be applied to the summed binned detector data and its output will be saved under <detector name>_variable in the binned hdf5 file, in addition to the full detector data.
Azimuthal integration

Detector definition section with azimuthal integration of the Rayonix:
# ##### DETECTORS ########################################################################
# List detectors to be cubed. Area detector have additional options such as threshold
# Full images will always be saved.
# More area detector can be defined following the same syntax, and adding them to varList
detDict = {'source':'Rayonix',
'full':1,
'image':1,
'thresADU':-1e5,
'common_mode':0}
pix_size = 176e-6
func_kwargs = {
'name': 'azav_pyfai', # must be the name of the smalldata_tools DetObjectFunc
'ai_kwargs': {'dist':1, 'poni1':960*pix_size, 'poni2':960*pix_size},
'npts': 512,
'int_units' : '2th_deg',
'return2d' : False
}
det_proc = [func_kwargs]
detDict['det_proc'] = det_proc
# make list of all variables to be added to the cube
varList = ['ipm_dg1/sum','ipm_dg2/sum', detDict]
The h5 resulting from this detector definition then contains:
Rayonix_azav (Array)Rayonix_data (Array)Rayonix_nEntries (Array)Rayonix_q (Array)
