JS9. Welcome to ASAIP — Astrostatistics and Astroinformatics Portal. Iraf, x11iraf and ds9 in ubuntu 32 bits [Archive] Hi! For those who don't know (probably the most) iraf is a software used by astronomers to reduce and process data (actually it has many more uses but this is the one I use most...). So probably, if you came across this by accident, you probably don't need a program that does this... For those of you who NEED this, and can't get to install it, here's the howto:): First of all, in case everything fails, you can use the installation guide that can be downloaded from here ( Now, prerequisites: Universe repository enabled. So let's begin installing this things IRAF The version of iraf that we will install is v214. Okay, so, to begin with, we will install the tcsh package (that's in the universe repository) sudo apt-get install tcsh Next, we make a folder were all of the iraf downloads will go (in order to keep things neat).

Mkdir ~/iraf cd ~/iraf Then, we download the iraf files. Next, I make iraf's directory tree: su iraf sudo . sudo . exit #! Astronomy Picture of the Day. Galaxy Zoo: Hubble.

What is SIMBAD, and what is it not ? % The purpose of Simbad is to provide information on astronomical objects of interest which have been studied in scientific articles. Simbad is a dynamic database, updated every working day. It provides the bibliography, as well as available basic information such as the nature of the object, its coordinates, magnitudes, proper motions and parallax, velocity/redshift, size, spectral or morphological type, and the multitude of names (identifiers) given in the literature. The CDS team also performs cross-identifications based on the compatibility of several parameters, in the limit of a reasonably good astrometry. Simbad is a meta-compilation built from what is published in the literature, and from our expertise on cross-identifications. Simbad is not a catalogue, and should not be used as a catalogue.
