M33 HI maps
The data come from the NRAO public archive (AT0206 and AT0268) and were reduced with CASA.
The data reduction is presented in Gratier et al. 2010 (http://adsabs.harvard.edu/abs/2010A%26A...522A...3G). 
You are free to use them but if you do, please make a reference to this article.
The data is available in 3 resolutions: 25", 17" and 12"
For each resolution there are 4 avalable fits files:
*-noise.fits : noise map
*-peak.fits  : peak temperature map
*-area.fits  : integrated intensity map
*-cent.fits  : centroid velocity (LSR)
*-fwhm.fits  : line width 

The intensity units are Kelvins, and the velocity units km/s.
