Instrument 2004 2005 2006 2007 Replacement

Mosaic 8K CCD Imager yes yes yes yes

ISPI 2K IR Imager yes yes -- -- NEWFIRM

NEWFIRM 8K IR Imager share share

HYDRA MOS (Fiber) yes yes yes: yes:

RC Spectrograph yes (SOAR)

Echelle Spectrograph yes ? ? (SOAR)

southern hemisphere us facilities 2004 2008
Southern Hemisphere US facilities 2004-2008
  • SOAR 4.2-m -> 6 x 6 arcmin field, Adaptive optics
  • Gemini 8m -> narrow-field MOS spectroscopy + OIR instruments, MCAO. Second generation instruments (2008-2009) still to be defined; may include KAOS.
  • Magellan 6.5-m (x 2) -> One telescope will have F/5 (like MMT), share Megaprime (24x24 arcmin)
  • SALT 11-m -> spectroscopy, specialized, no public time anticipated
mosaic ii
Mosaic II

Plusses

  • Good site, good telescope, good photometry
  • Reliable - (except we have a failed CCD)
  • Rapid filter change (< 10 seconds), lots of filters, fast shutter (10 ms uniformity)

Minuses

  • Image quality issues - telescope, corrector, environment?
  • Slow readout (1.5 minutes in 16-channel mode)
  • Capable, but complex data acquisition system - both hardware and software

SPIE 3355: CCDs - 487, Software - 497, Hardware -577 (1998)

mosaic ii improvements
Mosaic II - Improvements?
  • Replace the failed CCD (March 2004)
  • Improve the telescope imaging performance
    • Telescope primary mirror radial supports
    • Telescope active optics system
    • Dome environment
    • Evaluate corrector performance
  • Pipelines for data reduction
  • Data into NOAO archive
performance metrics
Performance metrics

“LSST” metrics:

(a) Faint Time window: A   / (psf)  1/2

(b) Faint stellar: A   / (psf) 1/2

(c) Faint resolved galaxies: A   / 1/2

Where sky noise limited exposures are assumed in all cases, and

A = Telescope primary area

 = Detector area

 = efficiency (everything from clouds to readout time)

(psf) = area of stellar point spread function

 = cycle time

 = background sky brightness

performance comparison
Performance Comparison

Faint Galaxy Performance: (A / 1/2)

LSST: 79

PanSTARS: 15

CFHT Megacam: 2.7

Subaru: 2.2

SDSS: 1.7

VST: 1.4

VISTA (IR): 0.93

CTIO 4m + Mosaic: 0.9
