'redpol3' is pretty much a drop-in replacement for redpol2. However, it has higher CPU and memory requirements, 
because it resamples the input data onto a 40 mas grid (to fix the IRCAL anisomorphism) and computes the
error images via a memory-intensive multi-dimensional standard deviation.

You'll need to comment out the /doflat in the call to fitsloader inside redpol3, just as you did for redpol2.



There is a slight addition to the /auto option. If instead of /auto, you set auto=2, then it will stop at
a few of the most important points in the script, but not as many breakpoints as when auto=0.



The output format is completely different. Each data set results in a single multi-extension FITS file:

Calibrated IRCAL polarimetry file format
	primary image:
	a data cube, with the following slices: I Q U P

	extension 1:
	uncertainty images, I Q U P

	extension 2: 
	exposure maps, I, Q, U

	extension 3: 
	polarization vector mask (OPTIONAL, not present most of the time)



The command 'redpol3_loadall, "STARNAME"' can be used to load all the data for a given star into ATV.
the command line options include:  
	/normalize    	plot normalized polarization vectors Q/I and U/I, instead of just Q and U vectors
	/snr		display the images in terms of SNR per pixel instead of counts per pixel.
	unsharp=	Unsharp mask the image by this many pixels before displaying
	/mask		Only display vectors for pixels where SNR > 1
