I-GALFA Policies

Acknowledgement text

All papers using I-GALFA data should use the following ackowledgement text (in LaTeX format):
The Inner Galaxy ALFA (I-GALFA\footnote{http://www.naic.edu/~igalfa}) survey data are part of the Galactic ALFA (GALFA) H I project observed with the Arecibo L-band Feed Array (ALFA) on the 305-meter William E. Gordon Telescope. Arecibo Observatory is a U.S. National Science Foundation facility operated under sequential Cooperative Agreements with Cornell University and a Consortium of SRI International, the Universities Space Research Association (USRA), and Universidad Metropolitana of Puerto Rico.

External data users

Investigators outside the I-GALFA team who wish to make use of the data before it becomes publicly available have their access subject to the approval of the I-GALFA membership, and their publications are subject to the rules of co-authorship given below.

Whether the data are public or not, we request that the acknowledgement text be included in any paper making use of I-GALFA data.


  1. The I-GALFA ``data team'' of observers + data processors consists of:

  2. The first science paper that any individual writes on any topic using I-GALFA data should include all data team members, unless they choose to withdraw their names because they feel they didn't contribute. This rule applies each time a new PI writes his or her first I-GALFA paper, regardless of whether the PI is an I-GALFA survey member or not.

  3. Data team co-Is are not required on second or later papers by the same individual using I-GALFA data. This is true regardless of whether the later paper is on the same topic as the first paper.

  4. I-GALFA survey members, whether on the data team or not, are free to join any declared science project or paper and become co-Is if they can demonstrably contribute to the project's scientific effort in ways other than observation or ordinary data processing (i.e. special processing for a particular purpose should be recognized).


The above policies can be changed with the approval of the I-GALFA science team membership.
