  Used from 2009-05-14 to present.

  The 1 change is highlighted in pink.

  Exp	Filter	Image	Event	Binning
  150s	White FC	8x8 image	8x8 event

  This finding chart is retried one more time if less than 100% complete. (This could be thousands of second after the GRB.) This finding chart will fail-over immediately to the following exposure if too bright for white.

  upto 350s
  Exp	Filter	Image	Event	Binning
  250s	U FC	12x12 image	12x12 event

  N.B. This finding chart will fail-over to 250s in the next available lentucular (8x8 in V and B), if too bright for U.

  20s	U		8x8 event
  20s	B		8x8 event
  20s	White		8x8 event

  N.B. if the previous upto 300s band does not run, the first filter in this sequence will be V as defined in UVOTMAN's FILTER_TO_USE variable.

  upto 950s
  Exp	Filter	Image	Event	Binning

  If the field is too bright for white, UVOT will try U and B in 12x12 image (UV: 12x12 imageevent) instead.
