ZTOOLS - Handy IDL routines
Working with IDl, everyone develops his or her own set of
handy tools. This is mine; and you're welcome to use it.
The tools are divided into several main categories, some of
which are better documented than others. They are:
- Images
- Stuff for manipulating scientific images. This is pretty
well documented and complete. The routines were designed with solar
physics in mind, but are applicable to a bunch of other applications.
They use a specific set of FITS tags to keep track of pointing information.
- Ground and SoHO
- Stuff designed to manipulate images from specific instruments --
in this case, instruments aboard the
SoHO spacecraft or on the Earth. Not very well documented, but
indispensible (to me anyway) in working with heterogeneous datasets.
- Vectors
- Stuff for manipulating vectors in four-space; in particular, for
doing tomography of solar images.
- Color
- Stuff for manipulating 8-bit color tables in IDL. Pretty primitive, but handy if you're good at reading inline comments.
- Util
- Some random utilities and other stuff that didn't really fit in
the other packages. Some of these routines are used by each of the other
packages.
You can download the whole lot from here, or use them directly from Sam Freeland's "ssw"
solar software tree. If you add or fix anything,
please write me and let me
know about it.
Use in good health!
