mapwavelength

pydis.mapwavelength(trace, wavemap, mode='spline2d')

Compute the wavelength along the center of the trace, to be run after the HeNeAr_fit routine.

Parameters

trace1-d array

The spatial positions (Y axis) corresponding to the center of the trace for every wavelength (X axis), as returned from ap_trace

wavemapbivariate spline object or image-like wavelength map

The wavelength evaluated at every pixel, output from HeNeAr_fit Type depends on mode parameter.

modestr, optional

Which mode was used to generate the 2D wavelength solution in HeNeAr_fit(), and specifically in lines_to_surface()? Options include: poly, spline, spline2d (Default is ‘spline2d’)

Returns

trace_wave1d array

The wavelength vector evaluated at each position along the trace
