IRAF needs to be started from the home directory, so type
> cd
> cl
and activate the ING package of routines
cl> ing
Move to a scratch directory
cl> cd /scratch/jktb
and make a directory for today and step into it
cl> mkdir 19980612
cl> cd 19980612
Use the EPAR (edit parameters) task to make the DAS_GET task aware of
the current FITS data directory (e.g. /obsdata/jkta/19980612)
ing> epar das_get
and use Cntr-D to exit the EPAR session. Now the command
ing> das_get last
will copy the latest FITS file that was created by the system over to
an IRAF file on the scratch directory, and it will display it automatically
on the XIMTOOL image display. Type
ing> help das_get
to get information on what other command line parameters the task
DAS_GET accepts. The IRAF task IMEXAMINE is a powerful tool to do a
quick check of your data with
ing> imexamine r234567
will display run r234567 and allows you some useful keystrokes with
the cursor on the XIMTOOL image display:
m gives pixel statistics of a small region around the cursor
s draws a surface plot
l plots a line
c plots a column
j fits a vertical Gaussian
k fits a horizontal Gaussian
r fits and plots a 2D Gaussian (useful for seeing measurements)
a fits a 2D Gaussian
v vector plot (press v twice)
e contour plot
q quit
