A New Python Pipeline for Reducing NIRSPEC Data Acquired at the Keck Observatory

The Keck Observatory Archive (KOA) (https://koa.ipac.caltech.edu) has just released a new data reduction pipeline (NSDRP) for data acquired with the Keck Observatory NIRSPEC cross-dispersed infrared echelle spectrograph. The pipeline is intended to reduce high-resolution (0.947 – 2.63 um) object spectra. … Continue reading

Astronomy Software (1986)

I admit that I have soft spot for these old videos. This one is from 1986. Now, the interfaces may seem primitive, yet the calculations are quite sophisticated – these types of programs are just as useful today.

The SAMI Data Archive: A Prototype of An Archive of the Future?

Astronomy data sets are not simply exploding in size – they are exploding in complexity too. Witness the data sets obtained from integral-field spectroscopy (IFS).  While the Sydney-AAO Multi-object Integral-field spectrograph (SAMI) survey has exceeded measurements of 1,000 galaxies, surveys such … Continue reading
