fried_parameter_to_seeing
- hcipy.atmosphere.fried_parameter_to_seeing(r0, wavelength=5e-07)
Calculate the FWHM of the seeing from the Fried parameter.
This uses \(\theta = 0.98 \lambda / r_0\), where \(\theta\) is the FWHM of the seeing, \(\lambda\) is the wavelength and \(r_0\) is the Fried parameter.
- Parameters:
- r0scalar
The Fried parameter in meters.
- wavelengthscalar
The wavelength in meters at which the Fried parameter is measured (default: 500nm).
- Returns:
- scalar
The FWHM of the seeing in arcsec at the specified wavelength.
