nubeam_geometry bug + spectra question

[BlehMaks]

Dear FIDASIM team,

1) I suspect that routine nubeam_geometry in python preprocessing has a bug in lines 1200-1203 There should probably be: 1200 phi_a = phi_s + nubeam["NLJCCW"] nubeam["NLCO"] (beta_a) 1202 src = np.array([rs np.cos(phi_s + beta_s), rs np.sin(phi_s + beta_s),zs]) 1203 aper_src = np.array([ra np.cos(phi_a), ra np.sin(phi_a),za])

or may be it would be better to make construction of phi_s the same as of phi_a and leave strings 
1202-1203 as they was

1200    phi_a = phi_s + nubeam["NLJCCW"] * nubeam["NLCO"] * **(beta_a)**
            phi_s = phi_s + nubeam["NLJCCW"] * nubeam["NLCO"] * **(beta_s)**
1202    src = np.array([rs * np.cos(phi_s), rs * np.sin(phi_s),zs])
1203    aper_src = np.array([ra * np.cos(phi_a), ra * np.sin(phi_a),za])

2) I have a question regarding to spectral calculations. I noticed, that all spectra have units "Ph/(s nm sr * m^2)". Does it mean that these spectra are local? If so, for what spatial point are they given? I thought, that FIDA synthetic diagnostic in FIDASIM should provide line-integrated spectra (as the real FIDA diagnostic), is not it?

Thank you in advance for your response!

Best regards, Maksim

@BlehMaks,

Thanks for finding the bug and suggesting a solution.

Your thought is correct, FIDASIM outputs the line-integrated spectra. If this were not the case, the units would have an extra factor of "m" in the denominator.
