Welcome to SED Machine Kitt Peak’s documentation!

SED Machine Kitt Peak is very low resolution (\(\frac{\lambda}{\Delta \lambda}\sim100\)) optical (365 - 1,000 nm) integral field (28”x”28”) spectrograph and an imager with a 6’ x 6’ field. The instrument was designed for rapid classification of supernovae from transient surveys and is based on the original SEDM on the Palomar 60-inch telescope.

To achieve this goal, the instrument was designed to have:

• Low resolution (\(R=\frac{\lambda}{\Delta \lambda}\sim100\)), sufficient for classification.

• High “Slit to detector” photon throughput.

• 0.1 mag precision spectrophotometry.

The project is funded by a consortium of private foundations and public institutions. The partners who will share time on SEDM KP are:

• Caltech

• University of Minnesota

• University of Maryland

• Northwestern University

• Space Telescope Science Institute

If you use SEDM data please use the following text in your published papers:

Based on observations obtained with the Spectral Energy Distribution Machine on the Kitt Peak 2.1-m telescope (SEDM-KP). The SEDM-KP team thanks the National Science Foundation and the National Optical-Infrared Astronomy Research Laboratory for making the Kitt Peak 2.1-m telescope available. SEDM-KP is supported by the Heising Simons Foundation under Grant No. 2021-2612, titled “The SEDM Kitt Peak Project,” and a collaboration including current partners Caltech, University of Minnesota, the University of Maryland, Northwestern University, and the Space Telescope Science Institute.

Many people were involved. A partial list of current members of the team are:

• Don Neill (Instrument Scientist, IFU pipeline automation, Caltech)

• Mickael Rigault (IFU pipeline lead developer, CNRS/IN2P3, France)

• Yashvi Sharma (Science operations, DRP, Caltech)

• Reed Riddle (SEDM-KP software/operations, Caltech)

• Josiah Purdum (Operations, Caltech)

• Michael Coughlin (Project Scientist, UMinn)

Here we document the instrument for observers and developers. Observers will want to refer to the Observer’s Reference below.
