There are several ways to obtain help for iCosmo.
1. If you require help on a particular routine you can try the inbuilt icosmo help (the majority of routines are supported).
IDL> icosmo_help, 'plt_pk'
; ***************// HELP BEGIN //**************
; PURPOSE: Plot power spectrum P(k) from cosmo structure
; INPUT: cosmo structure
; OPTIONAL INPUT: z: redshift of power spectrum
; linear: if set, only linear power spectrum is plotted
; overplot: overplot on previous plot
; color: color of line
; _extra: any keyword accepted by plot or oplot
;
; EXAMPLE:
; plt_pk, sv
; plt_pk, sv, z=2, linestyle=2, ,/linear,/over, linestyle=2
;***************// HELP END //**************

2. If the inbuilt icosmo help does not answer your question, or if you find a bug, please use the iCosmo discussion forum hosted by CosmoCoffee.
