The Y offset shows a linear dependence on temperature (FTDTDC):

- FUV - NUV Detector Y offset vs. FDTTDC : fdttdc-s12-dy.ps
- FUV - NUV Detector X offset vs. FDTTDC : fdttdc-s12-dx.ps

But the function varies with eclipse number. Grouped in 500 eclipse intervals, the offset varies in time:

- Y offset linear fits (500 eclipse intervals): dy_500_4by4_fits.ps
- X offset linear fits (500 eclipse intervals): dx_500_4by4_fits.ps

The Y offset at FTDTDC=29, plotted with eclipse number looks like:

- Y offset vs. eclipse: dy_500_fit.ps
- X offset vs. eclipse: dx_500_fit.ps
