[ATM] OSLO Tools

["Richard F.L.R. Snashall" <rflrs@rcn.com>]

I set out a couple of OSLO tools that I have found useful:

    http://users.rcn.com/rflrs/pho17.ccl
    http://users.rcn.com/rflrs/pipsf.ccl

The first command, pho17, sets up 17 photopically weighted
wavelengths over a sizeable chunk of the visual band.
Warning: This many wavelengths seems to give OSLO some
hiccoughs in its display functions, so some graphs may come
out in black instead of color.

The second command, pipsf, displays the Strehl ratio for a
given number of rings in the image.  If the system is not
symmetric, there will be up to eight points per ring.
Nominally, the rings are area spaced, e.g.: three rings will
come up as 0, 0.707 and 1.0 of the maximum image size.  A
negative argument will make it linear (0, 0.5 and 1.0).

These can be put into the private ccl directory, and compiled.
On my machine this directory is:

    C:\Program Files\OSLO\Light63\private\ccl\

Compiling is just:

    < Tools >< Compile CCL... >

and:

    [ private ][ all ]

and then I just accept the default compilation options.

I'm not really advanced in ccl programming, so you may find
some errors.  Please let me know if you do.
