CDS Outage 
Dear all,

As posted today on the CDS RSS feed, they encounter some technical issues preventing them to provide SIMBAD and Vizier services as usual.

As SearchCal, and somewhat ASPRO, rely on those services, we are not able to fulfill queries for the time being.

Rest assured the (great) CDS team is doing all its best to get back up !

We apologize for the inconvenience.

Negative visibilities at the edge of the bands 
Question: "For some channels from the beginning of the band,
I get visibility values far away from where we would expect them and in many
cases they have negative values​​. What is happening?"

Answer: The strange visibilities are usually at the very beginning of the K band, where there is some contamination by the H band (meaning that the fringe pattern given by the P2VM cannot be reliable). You should restrict your domain to a smaller wavelength range. Checking the P2VM with amdlibShowP2VM would be a good idea to see the possible overlap.
