Struct Group 

pub struct Group { /* private fields */ }

One group of a random-groups HDU.

The convention predates image extensions: rather than one array, the primary HDU holds a run of groups, each carrying a few parameters — a time, a baseline, a coordinate — followed by the array those parameters describe. It is mostly met in older radio interferometry data.

Implementations

impl Group

pub fn parameters(&self) -> &[f64]

This group’s parameters, in physical units.

PSCALn and PZEROn have already been applied, so these are the values the parameters stand for rather than the numbers stored.

pub fn parameter(&self, name: &str) -> Option<f64>

The parameter named by a PTYPEn card.

The standard allows a parameter to be split across several entries that share a name, so that a value needing more precision than the array’s type offers can be summed from its parts. Those parts are added here.

pub fn parameter_names(&self) -> &[String]

The names of this group’s parameters, from the PTYPEn cards.

pub fn data(&self) -> &[f64]

This group’s array, in physical units.
