Subject: mvd noise and kapton cable

Dear all,

	Last Friday night Hubert and I sat down and talked about our
notorious noise problem. As Hubert suggested I made 2 simple plots showing
linear relationship between noise level in packet and length of kapton
cable. "mvdeastnoise.ps" is kapton cable length vs. pedestal width in Mvd
east and "mvdwestnoise.ps" is Mvd west version. X axis has 4 points
each corresponding to OB, IB, IM, OT from shortest to longest. Y axis is
average pedestal width in ADC channel.
	More detailed but less intuitive numbers are in the attached file
"noisemap".
	Thanks.

Best regards,
Sangsu
