Aye Caramba!

October 20th, 2004 by admin

I moved and renamed the css file for this site instead of copying and renaming it. So, everything on this page looked absurd for probably 4-5 days. Why didn’t someone email and ask what the heck was going on? Ah well. Everything should be back to normal now.

The reason for the CSS mixup was that I am (for now) using the same blosoxm flavour and stylesheet for my personal blog, which I started late last week.

Using the Graphical help reader in IRAF

October 15th, 2004 by admin

<

p>Many people still type “help display” or what have you when they are trying to get info on an iraf package. There is a much better way in the latest versions of IRAF. Instead of help do this:

<

p>

help dev=gui

<

p>The dev=gui line is key, which opens up the help browser. You must be running IRAF in an xgterm for this to work. You can also type help dev=gui taskname and get help on a specific task or package.

<

p>You can also do an epar help and set the default behavior of device to gui so that you don’t have to type dev=gui ever again.

<

p>Once you use the graphical help browser you won’t go back. I often keep an instance of IRAF running that is always running xhelp, so I can read the documentation while I’m fiddling with parameters and such.
