XYZ

What does AIPS consider the x, y, and z axes? For example, XSMTH smoothes your data along the x axis. What on earth does this mean? I would think the z axis would be velocity.

I'd do an IMHEAD on your data file. The x axis is the first axis listed, the y axis is the second axis listed, and so on.

If you want to smooth another axis, you need to use the TRANS function to make that axis first.

this is, of course, only relevant for data cubes. (ie not uv files)
