Subject: Re: bi028c

Dear Lisa,

I would like to ask correlate bi028c and bi028d in an integration
time of 1 seconds. I do not mind about 2-s correlation for bi024b.
1-s average data from remaining 2 epochs is sufficient.
I did not change the previous .keyin file because 1000Mbyte/s data
output produced by 1-s average was still isseu to be discuessed about
its scientific merit at NRAO. Now I recognized that the 1-s average was
permitted. I appreciate if you kindly modify the average parameter
from 2s to 1s for bi028c and bi028d.

Best regards,

Hiroshi
