FLAMINGOS

FLAMINGOS at the MMT in February 2001
- Performance of Flamingos at the converted MMT's f/9 focus:
- A multi-object spectrograph/imager using a 2048 by 2048 HgCdTe array with
18 micron pixels
- Optics provide a scale reduction of 2.8
- 284 microns/arcsec at f/9 focus
- 0.18 arcsec/pixel at the detector
- 6.1 by 6.1 arcmin imaging field of view
- Collimated beam diameter is ~48 mm at f/9
- One grism available initially, with R~1000 for 2 pixel
(0.36 arcsec) slits
- 1.2-2.4 microns, at ~8.4 Angstroms/pixel
- Filters:
- J, H, K, K_short
- 0.9-1.8 microns
- 1.2-2.4 microns
- spare slot
- Several long slit widths are available. To do multi-object
spectroscopy, astrometry must be done ahead of time, and slit masks
manufactured.
- Predicted imaging performance:
- Assumed seeing: FWHM=3 pixels 0.53 arcseconds
- Aperture 1.2 arcsecond diameter

- Spectroscopic throughput
- Schedule: Flamingos will be available at the MMT for two
15 night runs per year. SAO observers will get 10 of these nights,
and Florida observers the other 5. The tentative schedule is
- June 2001 -- No multiobject spectroscopy (MOS)
- November 2001 -- Those wishing to do MOS should talk to B. McLeod by
June 30, 2001.
