Dragonfly Data Access

Data release 0.9

The first Dragonfly public data release, version 0.9, is now available. This release comprises data from the Dragonfly Nearby Galaxy Survey and the Coma cluster. To access these and all future data releases, please register for an account. Any revisions or future versions of the data products will be announced by email to registered members. Therefore, please do not forward data to others but ask them to register on this website.

Each field has both an R-band and a G-band image that are available to download. ​  Information about the Dragonfly G- and R-band filters, along with transmission curves, can be found in Abraham, R. G.; van Dokkum, P. G., 2014PASP, 126, 55A.

NOTE:  We have consciously labelled this data release 0.9 because we are continuously improving our data reduction procedures. We are in the process of re-reducing all data and will post a new release when this has been completed. ​
