2 questions.
First, is it possible to get the period vs. theta data out of pdm to plot with another application (like igi)? I did not find this data in the pdm batch file.

Second, is it possible to change graphics parameters for the graphs output by pdm? I need graphs that are printable for a paper (thicker lines, wider spacing in lettering, etc).

Thanks so much!

Not really. Through various long and nasty means it is possible to get the approximate values from the graphics metacode, but the task would need to be modified to directly output the computed values.

Second, is it possible to change graphics parameters for the graphs output by pdm? I need graphs that are printable for a paper (thicker lines, wider spacing in lettering, etc).

That is possible and (relatively) easier. Basically you need to create a custom graphics device with different pen-width and character parameters. See for example an earlier reply at http://iraf.net/phpBB2/viewtopic.php?t=63235

Hope this helps,
