Cormac,

I guess SgrA* at L-band is still weaker than ambient load. DAS for 64MHz
profile for L-Band looks fine with the level between sky and ambient load.

As I told you in the separate email, 70m is only available for limited
time, i.e. 10:00-13:00 and 17:45-19:30, we should take some lisk for Tid.
The antenna is yet to return to be operational and I won't be onsite to run
this, leaving Phil Pope in ops team to run this.

Cheers,
Shinji.
