Implementations

impl FitsLoader

FitsLoader struct for loading and accessing FITS file data.

The FitsLoader struct provides methods for loading and accessing data from a FITS file. It supports retrieving individual card values, all card values, image data, and converting the data to a Polars DataFrame.

Example

extern crate pyref_core;
use pyref_core::loader::FitsLoader;

let fits_loader = FitsLoader::new("/path/to/file.fits").unwrap();

// Get a specific card value
let card_value = fits_loader.get_value("CARD_NAME");

// Get all card values
let all_cards = fits_loader.get_all_cards();

// Get image data
let image_data = fits_loader.get_image();

// Convert data to Polars DataFrame
let keys = ["KEY1", "KEY2"];
let polars_df = fits_loader.to_polars(&keys);

pub fn new(path: &str) -> Result<Self, Box<dyn Error>>

pub fn get_card(&self, card_name: &str) -> Option<Card>

pub fn get_value(&self, card_name: &str) -> Option<f64>

pub fn get_all_cards(&self) -> Vec<Card>

pub fn get_image(&self) -> Result<Array2<u32>, Box<dyn Error>>

Retrieves the image data from the FITS file as an Array2<u32>.

pub fn to_polars(&self, keys: &[&str]) -> Result<DataFrame, Box<dyn Error>>
