Jack reported that he could not fix the problem right away. It may take 4 to 6 hours to solve the problem. Tonight is not a good time to do that. Therefore I plan to take data with single arm. I would like to discuss whether we fix it tomorrow or Thursday.
One more thing: Megan complained the background is too large. I plan to MCC to do a harp scan at the end of this slug(32) or next slug. Now it seems like a good time to do it before accessing the hall to fix the dipole.
