<div>Hi George </div>
<div dir="ltr"><br>
</div>
<div>Sorry, I notice the filters are installed only 42 channels. We will need 46 channels in the next experiment. Could you install the remaining filters on ch 35 - 39, and 41 - 42. These channels were not used previously, but will be used later. I don't think
we will be using channel 50 later, there the filter can be moved to one of the earlier channels. I am sorry if I was not clear in the previous email.</div>

<div>Hi George </div>
<div dir="ltr"><br>
</div>
<div>With the 47 filters(8 from BB and 39 Holly purchased), could you install them on the on the first 47 channel on the rack? This includes the 8 channels from BB and channels 9 to 47 on SBS?</div>
<div dir="ltr"><br>
</div>
<div>I believe we will only be using 46 channels in the next experiment. </div>
