12 Meter Telescope - Standard Spectra

The following table contains the most recent standard spectra from the 12m telescope. All observations have been made in position-switched mode with a relative OFF position in azimuth. In some cases, the OFF position may contain some emission, as no attempt was made to find a clean OFF. These spectra are meant to help observers check their observing setup and diagnose equipment problems. Questions about these measurements should be directed to Jeff Mangum. Thanks to Barry Turner and Harvey Liszt for acquiring the spectra taken 09/07/96 to 09/09/96.
