Some solar occultation observations are known to be affected by spacecraft pointing issues. Below is a list of file prefixes where a problem was detected. UVIS occultations and all diffraction orders with these filenames will be affected.

In the figures below, the transmittance for a single pixel is given as a function of altitude. Each detector bin is plotted individually (bin 0 is blue; bin 1 is orange; bin 2 is green; bin 3 is red).
The dotted black line shows the deviation from the nominal pointing - if the deviation is sufficient that the field of view of a detector bin moves off the solar disk, the transmittance will decrease. These features should not be interpreted as clouds or other properties of the Martian atmosphere.
