Some (generally high-brightness) level 1 ATM data contains scattered black flecks (can be quite numerous). Most frequent in band 7, but do occur in other bands. Example screenshot (from EUCAARI day 136):

Looking at the raw data with qcdisplay, the flecks aren't present, but there are short horizontal white lines. These seem to be less numerous than the black flecks and may or may not be related. Example screenshot (same flight):

Probably not worth doing anything about, since ATM is dying and due for replacement. First noticed as part of #115

Ensure we get the boresight data promptly and that all necessary lever arm measurements are taken.

This ticket is to describe the task of acquiring the 2007 boresight calibration.

There are two periods:

• start of year -> day 130 (ATM, Eagle, Hawk)
• (solas dust campaign, using atmospheric instruments)
• day 166 -> end of year (ATM, CASI, Eagle, Hawk)

This ticket has been created after the fact, so the dates are going to be wrong.
