tb_counts_to_countrate — 2D typed op

Data kinds: countscounts

Call: fullseye.apply(img, "tb_counts_to_countrate", a=0.5, b=0.5) (the 2-D model is one image plus two scalar knobs a,b∈[0,1])

*No figure: this op takes counts as input. A Studio program starting from an image cannot reach that type — see the runnable examples below for how it is used.*

Usage

Counts -> count rate `[Hz]. The inverse of :func:countrate_to_counts`.

> The detailed description below is the original text — the summary and the headings are translated.

Args:

counts: (N,) の非負計数。

gate_s: 積算窓 [s]。> 0。

Returns:

(N,) float64 の非負レート [Hz]。

Raises:

ValueError: 負の計数 / gate_s <= 0 / 形状不正 / 非有限。

2-D 進化レジストリへ橋渡しした reprconv の op `counts_to_countrate。実装は同じで、呼び出し規約だけ op(v, a, b) に合わせてある。agate_s(既定 0.001)を振る。b` は未使用。
