DKIST provides reference spectra for wavelength calibration in astronomy. The dataset includes a Solar spectrum covering 300 to 16,661 nm and a Telluric absorption spectrum from 350 to 5,000 nm. The solar data is derived from G.C. Toon's work, while the telluric lines come from synthetic spectra by T. Schad.
Use Cases
- Calibrate astronomical instrument wavelength using the Solar spectrum's 300-16,661 nm range as a reference.
- Correct for atmospheric absorption in observations by applying the Telluric spectrum's 350-5,000 nm absorption lines.
- Validate spectral models by comparing observed data against the provided Solar and Telluric reference transmittance values.
Strengths
- The Solar spectrum provides a broad reference range from 300 to 16,661 nm.
- The Telluric spectrum offers specific atmospheric absorption data from 350 to 5,000 nm.
- Data is sourced from cited, authoritative works by G.C. Toon and T. Schad.
Limitations
- The dataset's volume, row count, and file formats are unspecified, limiting assessment of its scale.
- No sample data or column definitions are provided, hindering immediate understanding of data structure.
- The temporal and spatial coverage for the original spectral measurements is not detailed.
