Follow-up Comment #33, sr #3124 (project relax): On a similar note, the wish for the 6 "bell-curves" was not produced. This was discussed in thread: http://thread.gmane.org/gmane.science.nmr.relax.devel/5158 Neither the file: file #20312: matplotlib_disp_theta_52_N.png or the attached file: matplotlib__52_N_R1rho_R2eff_theta.png gives the expected "bell-curves". I wonder if this is related to arctan function of calculating theta: ### From old scripts if omega1/OMEGA > 0: theta = 180/pi*abs(arctan(omega1/OMEGA)) else: theta = 180- 180/pi*abs(arctan(omega1/OMEGA)) ### This will be investigated, as also the production of R1rho_R2eff as function of the Spin-lock field strength. It could be that I have mis-understood something.
