There was a note with the filter saying that the filter had an irregular appearance, and when scanned in three different positions (once, then a 90degree rotation and again, and then another 90degree rotation and another scan) this graph resulted. This is a low resolution graph, of the same resolution as the 200-900Å graph on this page. The high resolution is of the filter in the third position, the exact same as the green trace in this graph, and the other low resolution graph.

Graphical View of Scan 4700-5300Å, one point per 1Å, 1 second spent on each point

Graphical View of Scan with 2000-9000Å, one point per 10Å, 0.1 second per point

1991

Central Wavelength	6732Å
Peak Wavelength	6751Å
FWHM	85Å
Max Transmission	13%

Plot of Transmission of the filter from 3000Å to 12000Å

Central Wavelength At Some Point Before 1991 = 6700Å
