Goodman Multi-Object Spectroscopy (MOS) mode

Goodman Multi-Object Spectroscopy (MOS) mode brings multiplex capability over a field of view of 3' x 5'.
Custom MOS masks are designed with a Mask Designing software, developed at UNC.
Goodman carrousel has 16 available positions for MOS masks. 
Installing MOS masks is a daytime task, like changing filters, and should be requested beforehand in the Instrument Setup Form [1], or by email to the Support Astronomer with copy (cc) to soarops@ctio.noao.edu [2], so our Observer Support staff also receives the request.

Click here to download the Goodman Mask Designing software (tested on Windows 7 and 10, 64-bit installations) [3].
Now users have the option to design their MOS masks by login into a CTIO machine which is already running the mask design software. Please contact your Support Astronomer for details on VPN access, procedure and passwords.
