Bases

CB73Basis <: SphericalBasis

A structure for accessing the radial basis elements of Clutton-Brock (1973).

Fields

• name::String: Basis name (default CB73).
• lmax::Int64: Maximal harmonic/azimuthal index (starts at 0).
• nradial::Int64: Number of radial basis elements (≥ 1).
• G::Float64: Gravitational constant (default 1.0).
• rb::Float64: Radial extension (default 1.0).
• tabPrefU::Array{Float64,2}: Potential prefactors array.
• tabPrefD::Array{Float64,2}: Density prefactors array.
• tabUl::Array{Float64,1}: Potential elements value array.
• tabDl::Array{Float64,1}: Density elements value array.

Description

The CB73Basis structure is used to access the radial basis elements as defined by Clutton-Brock (1973).

Example

```julia using Random

Creating an instance of CB73Basis

cb73 = CB73Basis( "CB73", # name 10, # lmax 5, # nradial 1.0, # G 1.0, # rb rand(10, 5), # tabPrefU rand(10, 5), # tabPrefD rand(5), # tabUl rand(5) # tabDl )

Accessing fields

println(cb73.name) println(cb73.lmax) println(cb73.G)

Warning

Ensure that the prefactor arrays (tabPrefU and tabPrefD) and the element value arrays

(tabUl and tabDl) have compatible dimensions to avoid runtime errors.

HernquistBasis <: SphericalBasis

• nradial::Int64: Number of radial basis elements (≥ 1).
• G::Float64: Gravitational constant (default 1.0).
• rb::Float64: Radial extension (default 1.0).
• tabPrefU::Array{Float64,2}: Potential prefactors array.
• tabPrefD::Array{Float64,2}: Density prefactors array.
• tabUl::Array{Float64,1}: Potential elements value array.
• tabDl::Array{Float64,1}: Density elements value array.
