# Theta

Features:[1] real-valued spherical harmonicsusing real coefficients[2] support flexible band intervals(l=0:dl:L) including both full bandSH (dl=1) and even order only SH (dl=2)[3] evaluate both function valuesf(theta,phi) and the derivativesof f w.r.t theta and phi. Can be usedfor finding peaks...
