tb_countrate_to_counts — 2D `typed` op

• Data kinds: counts → counts

• Call: fullseye.apply(img, "tb_countrate_to_counts", 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

Count rate `[Hz] -> counts counts. An exit of countrate` (reversible).

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

単位が変換の全内容: `[1/s] * [s] = [1]。gate_s` は積算窓の秒数で、

既定 1 ms。`counts` は「時間 bin ごとの光子数」の型なので、レート列を

そのまま counts と名乗らせると桁が 7 つずれたまま黙って通る

(`TYPE_CHECKS` はどちらも「非負の 1-D」としか見ていない)。

:func:counts_to_countrate と往復して実測 max|Δ| = 9.3e-10(値域が 1e3-1e7 Hz なので

相対 1e-16 = 倍精度の丸め 1 単位ぶん。絶対値だけ見ると大きく見えるので、

レートのように桁が広い量は相対で言う)。

Args:

countrate: (N,) の非負レート [Hz]。

gate_s: 積算窓 [s]。> 0。

Returns:

(N,) float64 の非負計数。

Raises:

ValueError: 負のレート / 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 `countrate_to_counts。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。a が gate_s(既定 0.001)を振る。b` は未使用。
