pg_utils.pg_model.expansion.pgvar_s

pg_utils.pg_model.expansion.pgvar_s = <pg_utils.pg_model.base.CollectionPG object>[source]

Radial placeholder functions of PG fields in 2-D disk.

These are the Fourier coefficients for use in combination with core.pgvar or core.pgvar_ptb, with omega*t+p*z the Fourier argument
