Fibre-Linked Array-Image Reformatter (FLAIR)

UKST Instrument - FLAIR is a decommissioned instrument and is no longer offered or supported at the UKST. The following information is provided for historical completeness.

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).
Instrument Scientist: No Instrument Scientist at present. Contact Head of Astronomy for information.
Manual: AAO UM-31.1 `FLAIR System User Guide' by Parker and Watson, 1995. Data processing of FLAIR 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.
