Struct LogRadialBinning 

pub struct LogRadialBinning {
    pub r_min_m: f64,
    pub r_max_m: f64,
    pub bins: usize,
}

Log-spaced radial bins: bin 0 is the disc [0, r_min), bins 1..=bins split [r_min, r_max) into bins bins of equal width in ln r. Metres.

Fields

r_min_m: f64

Inner edge of the first log bin (outer edge of the central disc), m.

r_max_m: f64

Outer edge of the last bin, m.

bins: usize

Number of log bins (the central disc is one more).

Implementations

impl LogRadialBinning

pub fn new(r_min_m: f64, r_max_m: f64, bins: usize) -> Result<Self, PsfError>

Validated binning.

pub fn len(&self) -> usize

Number of bins including the central disc, bins + 1.

pub fn is_empty(&self) -> bool

Always false: there is at least the central disc.

pub fn edge(&self, i: usize) -> f64

Inner edge of bin i (i <= bins + 1), m: 0, then r_min (r_max/r_min)^((i-1)/bins), and exactly r_max for the last.

pub fn edges(&self) -> Vec<f64>

All bins + 2 edges, m.

pub fn locate(&self, r: f64) -> Option<usize>

The bin of radius r, or None for r >= r_max (and NaN).
