Sample LWS Fringes

The plots below shows fringing in each of the 10 LWS detectors due to an extended source. The detectors are arranged in panels:

SW1 LW1
SW2 LW2
SW3 LW3
SW4 LW4
SW5 LW5

This source has a strong continuum and the zero point is off the plot on the (unreadable) y-axis of these plots, with only the top 20% or 30% of the emission plotted. The [OI] 63 um line can be see on a ripple peak in SW3 while the [CII] 158 um line is in a trough in LW4.
