Information on Service 'tco_hot_supergiants Datalink Service'

Spectral Archive of Hot Galactic Supergiants (TCO Node)

This resource provides a digital archive of one-dimensional (1D) optical spectra of hot galactic supergiants, obtained at the Three College Observatory (TCO). The archive is integrated into the Kazakhstan National Virtual Observatory (KazVO) data services and optimized for the IVOA Simple Spectral Access Protocol (SSAP).

Data Specification:

Observational Setup and Instrumentation:

Spectral Characteristics:

Data Reduction Pipeline:

Primary and scientific data reduction was performed within the IRAF (Image Reduction and Analysis Facility) environment using standard echelle spectroscopy packages.

Key Reduction Steps:

  1. Pre-processing: Bias frame subtraction.
  2. Extraction: Localization and extraction of individual echelle orders.
  3. Dispersion Relation: Wavelength calibration based on ThAr reference frames.
  4. Order Merging: Stitching of discrete spectral orders into a continuous 1D array.
  5. Kinematic Correction: Application of the heliocentric velocity correction (documented under the VHELIO FITS header keyword).
  6. Continuum Normalization: Continuum flattening achieved via high-order polynomial fitting.
