Enum BrightnessUnit 

pub enum BrightnessUnit {
    JyPerBeam,
    Kelvin,
}

Brightness unit of an image, which decides the flux scaling.

Variants

JyPerBeam

Jy/beam: scaled by Ω_new/Ω_old so values stay in Jy/beam.

Kelvin

Kelvin: surface brightness is conserved, so no scaling.

Implementations

impl BrightnessUnit

pub fn parse(bunit: &str) -> Option<Self>

Classify a FITS BUNIT string, or None if it is not recognised.

use convolve_rs::BrightnessUnit;

assert_eq!(BrightnessUnit::parse("Jy/beam"), Some(BrightnessUnit::JyPerBeam));
assert_eq!(BrightnessUnit::parse(" K "), Some(BrightnessUnit::Kelvin));
assert_eq!(BrightnessUnit::parse("Jy/pixel"), None);

pub fn from_bunit(bunit: &str) -> Self

Classify a FITS BUNIT string, warning and assuming Jy/beam if it is not recognised.
