ALMA Strawperson Zoom - E Array Equivalent

Physical Descriptions:

  1. This array is identical to the one in the NRAO strawperson design

Antenna Positions:

Antenna positions are given here in meters in UVCON format . The X and Y positions are with respect to a reference position on the 5 degree mask. To convert to SAM56 coordintes:

SAM56 E = 628340 + X
SAM56 N = 7453250 + Y

Snapshot Dirty Beam:


(Zenith snapshot dirty beam. The plotted grayscale ranges between -5% and +10%. NOTE No primary beam attentuation has been applied.
