Evaluations for different values of [Jmin] and [Jmax] of the [beta] and [gamma].
I have checked [the number of evaluations] for the different values of [Jmin] and [Jmax] in the [avg_params.dat].
Executed commands were like followings:
$./adda -orient avg CODE_171216_Euler/avg_params_beta_4_6_gamma_4_6.dat -shape chebyshev 0.7 12 -size 10

beta:
# default: min=0;max=180;Jmin=2;Jmax=4;eps=1e-3;equiv=false;periodic=false
# xy - symmetry plane: max=90;Jmax=3
# Do not use periodic=true since the function is multiplied by sin(beta) before integration.

Note
(Updated Dec. 24, 2017)
The above results were obtained using the adaptive approach.
Therefore the numbers of evaluations were same for different combinations of the (beta, gamma)'s (Jmin,Jmax) values.
See the following post for the detail:
avg_params.dat > different Jmin and Jmax with same [number of evaluations]
