SPARC is a database of 175 late-type galaxies (spirals and irregulars) with Spitzer photometry at 3.6 mu (tracing the stellar mass distribution) and high-quality HI/Ha rotation curves (tracing the gravitational potential out to large radii). SPARC spans a wide range in stellar masses (5 dex), surface brightnesses (4 dex), and gas fractions. On this webpage you can download SPARC data and access our scientific publications.

If you are using data from this website in your scientific publications, please cite the SPARC master paper.
