		double	deltaF,
		size_t	length,
		const REAL8FrequencySeries *	old
	)

static

Creates a new interpolated psd from an existing psd (if necessary).

The returned frequency series will have the specified values of f0, deltaF, and length. If the original frequency series old had the same values, this routine simply returns a pointer to the old. Otherwise, this routine allocates a new frequency series.

The interpolation in performed is linear-in-log (since a psd is positive-definite). Any component of the psd that is 0 is taken to be invalid, and any component of the returned psd that would depend on a 0 component of the original psd is also set to 0. Likewise, any components of the new psd that would require extrapolation of the original psd are set to zero. The routines defined here adhere to the convention that frequency components in which the psd is 0 are ignored.

Warning: If this routines returns a pointer to the original frequency series, it discards the const qualifier.

Note: The calling routine must test if the pointer to the psd returned by this routine is the same as the pointer to the psd passed to this routine to determine if the returned psd needs to be freed separately.
