Layout of VIRUS
The image below is a shuffle output for the globular cluster M3,
assuming a fully-populated array of 78 IFUs in VIRUS.
Here is an image of a current reconstructed image of VIRUS:
Here is the above image where we pack the IFUs and label them accordingly:
Below is the deployment plan for the full focal plane. For planning
purposes for Aug 1, we can approximately assume a rectangular grid,
with corners at IFUs = 012, 102, 017, 107:
