wavevector

pydl.pydlspec2d.spec1d.wavevector(minfullwave, maxfullwave, zeropoint=3.5, binsz=0.0001, wavemin=None)

Return an array of wavelengths.

Parameters:

minfullwave : float

Minimum wavelength.

maxfullwave : float

Maximum wavelength.

zeropoint : float, optional

Offset of the input wavelength values.

binsz : float, optional

Separation between wavelength values.

wavemin : float, optional

If this is set the values of minfullwave and zeropoint are ignored.

Returns:

numpy.ndarray

Depending on the values of minfullwave, binsz, etc., the resulting array could be interpreted as an array of wavelengths or an array of log(wavelength).
