    1 These are the types of features I have seen in the detrended images from 090712.  
     1These are the types of features I have seen in the detrended images from 090712. I've classified them as these types:  satellites streaks, star artifacts, vertical streaks, striped vertical streaks, vertical edge streaks, horizontal edge streaks, and tilty streak explosions.  The left(top) image is the mask, and the right(bottom) image is the fits image. These are not exactly to scale.  Most of the streaks that I have seen (that are not part of the explosions) are the '''vertical streaks'''.

    12 vertical streaks (these do not land on the edge of the chip, and might run through the length of it, but usually do not):

    14 vertical streaks that oscillate between bright and dark:

    16 vertical streaks that land on the edge of the chip (see the tilty streak explosion), these do not always happen near a tilty streak explosion, but it makes it easier to verify the location

    18 tilty streak explosions:

     44See tilty streak explosion for an example, these do not always happen near a tilty streak explosion, but it makes it easier to verify the location (see the red streaks on the explosion).

     48These are also in the tilty streak explosion (green and blue), also do not need to be near a tilty streak explosion.
