Module astronomical 

Astronomical file formats

Provides support for astronomy and astrophysics data formats:

• FITS: Flexible Image Transport System
• VOTable: Virtual Observatory Table format
• HDF5-based formats used in astronomy Astronomical file format support

This module provides support for file formats commonly used in astronomy, astrophysics, and space science research.

Supported Formats

• FITS: Flexible Image Transport System - standard format for astronomical data
• VOTable: Virtual Observatory Table format for tabular astronomical data

Examples

use scirs2_io::formats::astronomical::{FitsFile, FitsTableReader, VOTable};
use scirs2_core::ndarray::Array2;

// Read FITS file
let fits = FitsFile::open("hubble_image.fits")?;
let header = fits.primaryheader();
let image: Array2<f32> = fits.read_image()?;

// Access header values
let exposure_time = header.get_f64("EXPTIME")?;
let telescope = header.get_string("TELESCOP")?;

// Read FITS table
let tablehdu = fits.gethdu(1)?;
let table_reader = FitsTableReader::new(tablehdu.clone())?;
let column_data = table_reader.read_column("FLUX")?;
