Struct ArmCountPrediction 

pub struct ArmCountPrediction {
    pub neutron_signal: Vec<f64>,
    pub background: Vec<f64>,
    pub total: Vec<f64>,
    pub window_loss: f64,
}

Signal, additive background, and total expected counts for one measured arm.

Background is expressed directly in the detector bins of that measurement and is added after source attenuation and instrument response. It is not the SAMMY additive transmission curve, and it is not convolved a second time by the instrument response.

Fields

neutron_signal: Vec<f64>

Neutron counts produced by source, sample, and instrument response.

background: Vec<f64>

Independently supplied additive expected counts in the measured bins.

total: Vec<f64>

Complete expectation, neutron_signal + background.

window_loss: f64

Expected neutron counts lost outside the acquisition window, carried through from TwoArmCounts.

The pipeline-map contract (R5·7) requires the acquisition-window loss to stay disclosed rather than renormalized away. Forming a total expectation is exactly where that report would otherwise be dropped, so it travels with the arm it belongs to. Only the neutron signal can leave the window: a background template is supplied already binned into the acquisition, so it contributes no additional loss.

Trait Implementations

impl Clone for ArmCountPrediction

fn clone(&self) -> ArmCountPrediction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ArmCountPrediction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ArmCountPrediction

fn eq(&self, other: &ArmCountPrediction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
