Function Documentation

void add_rss_wcs	(	ltl::FitsOut &	O,
		float	w1,
		float	dw,
		bool	logw,
		const std::string &	label
	)

Add a WCS to a FITS file with 1D spectra. The zeropoint is w1, the wavelength increment dw, and logw indicates logarithmic wavelength binning.

The first axis will be labeled label, the second axis will be labeled fiber id.

Add a WCS to a FITS file with multiple 1D spectra

	)

Add a wcs to a 2D (reconstructed) image of the sky. ra_deg, dec_deg, and pa are right ascension, declination and position angle on the sky cx and cy are the reference pixel corresponding to ra_deg and dec_deg pixscale_X is the pixelscale in degrees per pixel along x and y axes
