irfpy.jdc.energy0

Draft energy module for JDC.

JDC performance in the proposal indicates that the energy range is 1 eV to 41 keV. For simplicity, the full angle energy 25 keV is not considered so much here.

The energy resolution is 12% and energy step is 128. Indeed, these values will give “overlap” of the energy coverage.

Here, as the first example, I just do not consider the energy resolution, just a “central value”. If the lowest energy step gives 1 eV and the highest 41 keV, the energy resolution will be 8.65% for 128 steps.

irfpy.jdc.energy0.getEnergy()

Return the energy table in eV.

Returns

Energy table with (128,) shape

Return type

np.array

>>> jdc_enestep = getEnergy()
>>> print(jdc_enestep.shape)
(128,)
>>> print(jdc_enestep[0])
1.0
>>> print(np.round(jdc_enestep[127],1))
41000.0

irfpy.jdc.energy0.getRange()

Return the upper and lower limit of the energy table.

This provides the energy range of the specific energy step. No gap between the energy steps.

Returns

Energy range table with (2, 128) shape

Return type

np.array

>>> jdc_enerng = getRange()
>>> print(jdc_enerng.shape)
(2, 128)
>>> print(jdc_enerng[:, 0])  # Energy step 0 range
[0.95904599 1.04270286]
>>> print(jdc_enerng[:, 1])  # Energy step 1 range
[1.04270286 1.13365707]

irfpy.jdc.energy0.getBound()

Return the bounds of the energy table. 129 elements.

Energy step 0’s lower bound is getBound()[0]. Energy step 0’s upper bound, which is identical to energy step 1’s lower bound, is getBound()[1].

>>> jdc_bnd = getBound()
>>> print(jdc_bnd.shape)
(129,)
>>> print(jdc_bnd[0])  # Energy step 0 lower bound
0.959045989666
>>> print(jdc_bnd[1])  # Energy step 0 upper bound & 1 lower bound
1.04270286386
