It is a major goal of the GALFA-HI Survey team to provide data cubes to the astronomy community. The survey is currently in progress and data reduction routines are still being written, implemented and tested. As such, no reduced data are currently available to the general public. If you are interested in specific data from the GALFA-HI survey please contact us: depending upon the state of the data in the region of interest, we may be able to provide you with preliminary data. The survey is split up into 225 data regions (5 in dec by 45 in RA) with some overlap. Each region is 512 arcminutes (8 8/15 degrees) on a side, oriented along small-circle RA and Dec. Each region has three data products: A 'wide' band cube with 0.74 km/s resolution from about -750 to 750 km/s V_LSR, a 'narrow' band cube with 0.18 km/s resolution from -190 to +190 km/s and 512 individual dec slices, stepped in RA, with 0.18 km/s resolution from 750 to 750 V_LSR. The layout on the sky is as shown below:  We have so far covered a significant fraction of the sky, with many cubes having been completely imaged in at least one of our observing modes. No region of the sky has been observed to the depth and precision we expect in the final survey, but the below plot shows the fractional area of each tile that has been observed by at least one observing mode:  The below figure shows the LAB HI survey (0.6 deg resolution; Kalberla et al. 2005) with the entire Arecibo sky within the red lines. The sky covered by TOGS commensal with ALFALFA is shown by the dark blue boxes and TOGS commensal with AGES by the light blue boxes. The entire Arecibo sky will be covered by TOGS2 (commensal with GALFACTS).  For the M33 data cube click on the following link: http://www.astro.columbia.edu/~mputman/M33only.fits.gz |
