[daip] BS037 data

[Leonia Kogan]

Dear Sara,

I have deeply discussed your problem with our analysts and we found the 
following bad (for you result :( ).

When I designed the observation at BS037 I planed to use VLA to 
determine absolute position of the methanol maser sources. I do not 
remember now how I planned to do it.

But VLA was busy at the time of my project and I was offered "some" VLA 
antennas to observe my sources using the concept of subarray.
Reducing my data using only VLBA antennas, I came across the serious 
problems to reach a reasonable result and I stopped it before looking at 
the VLA data. Now, when me with our analysts looked at the VLA data, we 
found that only one VLA antenna was lent to me!!

Unfortunately only one VLA antenna observed at different frequency is 
unusable. :(
Actually our analysts could load the VLA data using FILLM and confirmed 
the presence of only one antenna.

By the way you wrote:
"your BS037 program is one of the very few continuum maps of the HII
region.."
Where did you see the BS037's program continuum maps of the HII
region?
