#Preceding images
----------------

Immediately before was a bias image; before that were subarrays (UVIS narrowband throughput monitor)

#Following images
----------------

Image following 56456 appears to be clean or it has identical bowtie level as the comparison flat, pretty unlikely
iu200403r_08087212327.div.iu200403r_08097201126.fits completely clean

NOTE: 56456 may be mis-ID'd as having bowtie
Ratios examined which contained iu200402r_08097201126 imply it is bowtie free
or, the frames it was ratio'd with have exactly the same level of bowtie
iu046203r_08090042209.div.iu200402r_08097201126.fits flat; no bowtie ---> so 56456 bowtie free? or same bowtie as 54567
iu046205r_08090042209.div.iu200402r_08097201126.fits flat; no bowtie ---> so 56456 bowtie free? or same bowtie as 54568
iu200402r_08097201126.div.iu202202r_08111141319.fits appears clean but lots of QE structure
iu202202r_08111141319.div.iu200402r_08097201126.fits faint bowtie? but lots of QE structure
iu202202r_08111165419.div.iu200402r_08097201126.fits appears clean but lots of QE structure

But there appears to be a hint of the bowtie in the plain image (56456, iu200402r_08097201126)
