Template:Notation

Standard notation header for any equation-bearing page. Documents ψ-convention, metric signature, and unit system in a compact box.

Usage

{{Notation
| psi_convention = lowercase ψ = field amplitude; uppercase Ψ = energy density T⁰⁰(ψ)
| signature      = mostly-plus (−,+,+,+)
| units          = SI
| index_convention = Greek μ,ν,ρ,σ ∈ {0,1,2,3,4} (5D); Latin i,j,k ∈ {1,2,3} (spatial)
| extra          = ℏ = c = 1 unless noted
}}

Parameters

Parameter	Notes
psi_convention	How ψ vs Ψ vs φ are used on this page. (Optional.)
signature	mostly-plus (−,+,+,+) or mostly-minus (+,−,−,−). (Optional.)
units	SI, natural (ℏ=c=1), Gaussian, etc. (Optional.)
index_convention	optional — Greek/Latin index ranges.
extra	optional — any other site-wide convention notes.

All parameters are optional. If none are supplied, the box renders an empty body.
