Function Documentation

void compute_Io_mask	(	size_t	ntimes,
		size_t	nwavelens,
		float *	wavelens,
		float **	Ios,
		size_t	mask_nwaves,
		float *	mask_waves,
		float *	mask_buffer,
		byte_t *	Io_mask
	)

Compute the Io mask used by the Io Filter.

This function assumes that the Io_mask has already been initialized.

size_t find_nearest_wavelength	(	size_t	nwavelens,
		float *	wavelens,
		float	wavelen
	)

Find the index of a wavelength in an array of wavelengths.

Parameters:

nwavelens	- number of wavelengths in the wavelengths array
wavelens	- array of monotonically increasing wavelengths
wavelen	- the wavelength to look for

Return values:

index

of the wavelength that is closest to the specified value.
