Properties of the initial-guess sampling.

Parameter	Estimate	Width	Distribution
q_as	0.2	0.2	Gaussian
Δν	Δν₀ (l = 0-fit)	0.03 ⋅ Δν₀	Gaussian
ΔΠ	ΔΠ_N (N-integral)	0.03 ⋅ ΔΠ_N	Gaussian
ϵ_p	$ϵ_{p, 0} + \frac{1}{2}$ $\epsilon_{\mathrm{p},0}+\frac{1}{2}$	0.7	Uniform
	(ϵ_p, 0: l = 0-fit)
ϵ_g	0.5	1.2	Uniform

Notes. For Gaussian distributions, the width refers to the standard deviation of the Gaussian; for uniform distributions, the limits were set to estimate±width. Since q can physically only take positive values, all instances in which the Gaussian sampling returned a value < 0 were resampled with a uniform distribution over [0, 0.8].

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
