Miscellaneous useful information

IRAF

The image analysis package IRAF is available. To get going, make a directory called ``iraf'' in your top-level directory, cd into it, and then type ``mkiraf''. It is possible to control the APT from within IRAF scripts, ask Michael Ashley for details.

xsky

The program ``xsky'' gives a very nice display of the sky. Just type ``xsky'' to get going, wait 30 seconds for it to start up, and then play with the various options. You can add additional catalogs (e.g., the SAO catalog; use the ``Catalog'' button) and change the magnitude limit of the stars that are displayed (use the ``Info'' button). Clicking on a star or object will give you information about it. ``xsky'' uses the J2000 equinox. See ``man xsky''for documentation. ``xsky'' is particularly useful at identifying fields when used in conjunction with the ``-ul -rot 1' options of SAOimage (so that both displays are orientated in the same way).

``xsky'' does not currently work on the Xterminal due to a font problem.

``xsky'' does not work if it can't allocate lots of colours. So, it is best to start it up before running programs like ``xv'' and ``xmosaic''.

Mail

e-mail works on mistral.

Spiders

There are lots of red-back spiders in the vicinity of the APT building. These spiders can cause severe pain, but not death. Two funnel-web spiders has been seen (and dispatched) in the APT control room (one by Michael Ashley in June 1994, and one by Oliver Prouton in April 1995). Funnel-webs are a few centimetres across, black in colour, and will prepare to strike with two fangs if approached. They are extremely dangerous and can cause death. It is hypothesised that the funnel-webs were carried to SSO by vehicles travelling from Sydney during the construction phase of the AAT.
