All wavelengths are in the heliocentric reference frame.
The vector provided by the OAO-3 project is used by default. If not available, a background is derived from a table of standard backgrounds stored as a function of orbit number. 16-bit integer Number of points coadded at each wavelength. The scatter in net flux values about the mean at each wavelength. Origin of documentation.
