There is a new IRAF package available on tycho at Apache Point. The package is called 'apo' and can be accessed from the main cl package on tycho. This will serve as a storage are for tasks of use for reduction and analysis of APO science and engineering data. Take a look and see what's there. There are currently two tasks that might be useful - 'size' and 'grimcombine'. There is also a sub-package of 'apo' called 'lens.' This contains a number of tasks that were developed for the gravitational lens monitoring program. Some of them may be of general use though, so have a look at them: SIZE If you've ever had that annoying problem of the cursur ending up in a garbled mess in the middle of your window rather than at the bottom like it should be, or an epar that scrolls off into la-la land, then just run size (type size). This will automatically correct the probelm. If at any time during your session you resize your window, just type size again. GRIMCOMBINE Grimcombine is just a special form of imcombine that is especially useful for looking at data from my grim focus script (grimfoc.tcl in ~bergeron/tcl). You can feed it your sequence of images (focus images) and it will generate a median sky frame from the set, subtract that sky from each image, and then average the frames together. In the case of a focus sequence, you end up with something that looks like a DIS focus frame. This task will work on *any* set of images, not just grim data. To run it just load the apo package and epar grimcombine. I'll get a help file for this task built soon. For a set of 9 grim images it takes 10-15 seconds to run. If you have written an iraf script that you think might be of use to the APO community let one of the operators or Jim Fowler know and we can put it in the package for you.
