Extracting spectra from AAOmega observations

AAOmega (at Anglo-Australian Observatory) observations can be reduced with 2dfdrv4 tool pretty much very easilly. But the reduction ‘s final output is a combined fits image which includes all spectra from the 400 fibers. So, the user has to extra by himself/herself the spectra individually and this has been frustrating (at least for me…). 1. […]

AAO’s Configure – fiber arrangement for AAOmega

AAOmega is one of the instruments of Anglo-Australian Observatory. It is a multi-purpose, bench mounted, fibre fed, double-beam spectrograph with two main observing modes: i. Multiple-object spectroscopy using the existing 2dF top, ii. Integral field spectroscopy at Cassegrain focus. In order to use the multiple-object mode you need to know which fiber goes where. Configure […]

Installing AAOmega’s data reduction program – 2dfdr

The AAOmega spectrograph of Anglo-Australian Observatory uses the 2dfdr v4 data redution package (version 4 removes most dependencies on STARLINK packages, earlier version will need also the STARLINK to be installed, so it is not recommended). After downloading the necessary file (ftp and get 2dfdr-linux_x86_RH_5_3-4.0.tgz) you just need to set an environment variable and run […]
