please see the User Manual and SPIE papers.|
Wavelength range: Fixed format covering 388 to 668nm.
Slits and Resolving Power:
Scale and Dispersion: 0.09 arcsec/pixel, ~0.015 Angstroms/pixel
|Width (")||Length (")||Resolving Power
|0.7||3.9||N/A||For Wide Flats|
|0.3||-||N/A||Pinhole; For Focus|
Velocity precision: under 1 meter/sec, based on data taken as of
Detector: STA0500A CCD, 4K x 4K, 15 micron pixels.
Slit viewer field of view: 38x38 arcsec
|Speed||Read Noise (e-)||Gain (e-/ADU)
||Readout time (sec)|
Calibration sources: Thorium Argon lamp, Quartz lamp, Iodine
Practical faint magnitude limit: Somewhere between V=15 and V=16,
limited by star visibility in slit viewer
Efficiency: Peak instrumental efficiency is around 23%
Instrumental efficiency from entrance aperture to detector.|
This does not include slit losses, telescope efficiency, or atmospheric
absorption, but does include the QE of the CCD.
AB magnitude zero point.|
This is the AB magnitude of an object from which one expects to receive 1
electron/sec/Angstrom at 1 airmass without a slit. Depending on the airmass,
seeing, and choice of slit, actual count rates will be lower.
