validate_wavelength_array¶
- speclite.filters.validate_wavelength_array(wavelength, min_length=0)[source] [edit on github]¶
Validate a wavelength array for filter operations.
This function will not perform any copying or allocation if the input is already a numpy array or astropy Quantity.
- Parameters:
- wavelengtharray
A 1D array of strictly increasing wavelength values with optional units. If units are included, they must be convertible to
default_wavelength_unit. Otherwise, thedefault_wavelength_unitis assumed.- min_lengthint
The minimum required length of the wavelength array.
- Returns:
- numpy.ndarray
Array of validated wavelengths without any units, but with values given in
default_wavelength_unit.
- Raises:
- ValueError
Wavelength array is not 1D, or not strictly increasing, or below the minimum length.
- astropy.units.UnitConversionError
The wavelength array has units that are not convertible to
default_wavelength_unit
