| 738−788 | 07 Feb. 2013 | p1(fwhm) + p2(par) |

Notes. The baseline functions of the form pj(i) denote a polynomial of order j in parameter i, where i can be the parallactic angle par, its cosine cos(par), the differential parallactic angle from one exposure to the next dpar, and the PSF or spectral full-width at half maximum fwhm. off refers to an offset included at the change in exposure time for the 5 December 2012 observations.
