loads a preset combination of g₀, σ, N, and τ for a named detector scenario; overwrites current slider values

maximum detection probability: an animal sitting on a detector is captured with probability g₀; updates live

detection scale (km): governs both the home range size and how detection probability falls off with distance from the activity centre; updates live

true number of animals in the arena; takes effect on Reset

number of capture occasions per run: more occasions increase data volume and improve D̂ precision; takes effect on Reset

named movement scenario: overwrites τ; use to quickly set realistic animal mobility

home range crossing time (occasions): low τ = restless animals covering the range quickly, high τ = sedentary; updates immediately

site fidelity multiplier: values above 1 shrink the effective home range, tightening movements around the activity centre; takes effect on Reset

spatial layout of the detector array: Grid = regular lattice, Random = random placement, Click to place = manual; takes effect on Reset

grid dimension: places n_grid × n_grid detectors on a regular lattice; takes effect on Reset

Show detection surface

Overlays p(x,y) on the sim. Updates live when g₀ or σ change, or when detectors are added or removed.

Show activity centres

True centres (•) and estimated centres (×) per animal. Estimated = mean of capturing detector positions; converges toward truth as k grows.

g₀ and σ update live. All other parameters take effect on Reset. τ takes effect immediately.

τ = occasions to cross home range radius. Low τ → restless; high τ → sedentary.
