Accepting Directories

Alright, now that I've finally adjusted to moving from Caltech to home (and learnt how to deal with my dust allergies), IPhot now accepts directories as well as individual .FITS files in one directory. (I guess I have to change the usage() description of IPhot as well.) Here are the three different ways IPhot can process and find .FITS files in command line:

  1. By default, if no additional argument is written after 'IPhot', IPhot will assume the directory is the current directory. Any .FITS files in this directory will then be processed. Let's say you have a file called fitsimage.fits in this directory. Typing in IPhot will give you this:

    C:\[Your path here]> IPhot

    The image will open up and you'll be able to click on it and such just as before.
  2. You can specify a directory after IPhot. IPhot will go through this directory and process all the .FITS images in that directory.

    C:\[Your path here]> IPhot "C:\\Example\\Path\\To\\Your\\Images\\" -d 0.95 -t 4

    ImageFromThisPath.fits and any other .fits images will then show up on the screen like before, and will create contrast curves in the way specified by the options following the path. You can still press 'q' to quite or any other key for the next image. Note the specific way you have to type the paths - it has to have quotes around it (since it's a string, and also because some path names have spaces inside them, like "Documents and Settings" that PC's use), and you should also write double \\'s to be safe.
  3. This is the way I originally implemented this program to handle .FITS files.
    C:\[Your path here]> IPhot CK00012_snap_20110412.fits -d 0.97 -t 5

    The program will go through the .FITS files one by one and create contrast curves for them (if you make it do so) according to the options following the .FITS files. Note that you can still type in multiple individual .FITS file names. 
I gotta say, this was pretty fun to work on. But I'm still not done with my point sources finder -- it's rather reluctant to actually find some point sources (simulated or 'real' ones) -- so I still can't test this code very extensively to make sure that it works brilliantly. For now though, I'll say that it seems to work fine.
