Scientific paper

A straightforward 'multiple-read' software algorithm is described, which reduces the read noise of a state of the art IR array detector by a factor of order 5. This gain in performance is demonstrated directly in a low-background application using the KPNO Infrared Grating Spectrometer for a measurement of vibrationally excited molecular hydrogen emission from the protoplanetary nebula CRL 2688.
