Struct marlu::pos::lmn::LMN[−][src]

pub struct LMN {
    pub l: f64,
    pub m: f64,
    pub n: f64,
}

Expand description

(l,m,n) direction-cosine coordinates. There are no units (i.e. dimensionless).

This coordinate system is discussed at length in Interferometry and Synthesis in Radio Astronomy, Third Edition, Section 3: Analysis of the Interferometer Response.

Fields

l: f64

l coordinate [dimensionless]

m: f64

m coordinate [dimensionless]

n: f64

n coordinate [dimensionless]

Implementations

impl LMN

pub fn prepare_for_rime(self) -> LMN

Subtract 1 from n and multiply each of (l,m,n) by 2pi. This is convenient for application with the radio interferometer measurement equation (RIME), as performing some multiplys and subtracts ahead of time results in many fewer FLOPs.
