| In Brief: |
FLAIR is a multiobject feed for the FISCH spectrograph at the UKST.
Up to 91 objects can be observed simultaneously, covering 40 square degrees
of the sky. Fibres are cemented to negative copies of Schmidt plates using
a semi-automated FLAIR fibre positioning system (AutoFred). |

data is explained in 'FLAIR Data Reduction with IRAF', available
online. |
Fact Sheet:
|
See FLAIR web page
|
| Detector: |
Thinned back-illuminated EEV CCD-02-06 with 578 x 400 22 um square
pixels. |
| Focal Station: |
Fibres mounted in plate holder in Schmidt Telescope. Two plate holders
are available. One (14/5) has 91 fibres with 6.7 arcsec diameter core.
The other (14/6) has a bundle of 73 6.7 arcsec diameter fibresand a bundle
of 70 3.7 arcsec diameter fibres. These two bundles cannot be used
simultaneously. |
| Spectral Resolution*: |
450 - 3000 (a range of gratings are available) |
| Sensitivities: |
For a galaxy B=17, in 2000 sec will produce 1100 ADU in the object,
and 720 ADU in the sky, resulting in S/N=25. However to remove CRs, a minimum
of 2 x 2000 sec is required for galaxy redshift work to B = 17 - 17.5. |
|
*Spectral Resolution R measured as lambda/delta_lambda, delta_lambda =
FWHM unresolved line, usually 2 pixels.
