subroutine	f0_update_analytic_f0 (grid, sp, psn)
	Updates the analytic part of the total-f distribution function by filtering the density, flow and temperature moments from the particle set. This is achieved by computing the density, temperature, and flow moments of the particle set, \(\delta n\), \(\delta T\) and \(\delta u\). This defines two Maxwellians \(f_M(n_0,u_0,T_0)\) and \(f_M(n_0+\delta n,u_0+\delta u,T_0+\delta T)\), the difference of which is subtracted from the particle weights and subsequently added to the analytic distribution function.

Updates the analytic part of the total-f distribution function by filtering the density, flow and temperature moments from the particle set. This is achieved by computing the density, temperature, and flow moments of the particle set, \(\delta n\), \(\delta T\) and \(\delta u\). This defines two Maxwellians \(f_M(n_0,u_0,T_0)\) and \(f_M(n_0+\delta n,u_0+\delta u,T_0+\delta T)\), the difference of which is subtracted from the particle weights and subsequently added to the analytic distribution function.

Parameters

[in]	grid	XGC grid data structure, type(grid_type)
[in]	sp	Particle data object, type(species_type)
[in]	psn	XGC field data object, type(psn_type)
