Well, just execute the commands after you have switched
to the PostScript device driver:

thisDevice = !D.Name
Set_Plot, 'PS'
Device, Filename='myplot.ps'

OpenR, lun, 'yourfile.dat', /Get_Lun
rows = File_Lines('yourfile.dat)
header = ''
data = FltArr(3,rows-1)
ReadF, lun, header, data
Free_Lun, lun
f = Reform(data[0,*])
period = Reform(data[1,*])
gamma = Reform(data[2,*])
Contour, gamma, period, f, /Irregular, NLevels=10

Device, /Close_File
Set_Plot, thisDevice

There are lots of things to know about configuring
the PostScript device with the DEVICE command, but
I typically just use my program PSCONFIG to allow
the user to do it interactively. Saves a lot of
wear and tear. :-)

keywords = PSConfig(Cancel=cancelled)
IF cancelled then RETURN
thisDevice = !D.Name
Set_Plot, 'PS'
Device, _Extra=keywords

You can find the programs for PSCONFIG here:
