Recommended Criteria for ALFALFA Science
The following guidelines were adopted following the ALFALFA team
meetings in May and June 2005.
0.0     A member of the ALFALFA collaboration who wishes to work on a specific
project that relies on ALFALFA data should inform the Oversight Committee (OC).
A description of the project scientific goals, instruments to be used and
extent of use of ALFALFA data should be indicated, as well as a timetable for
completion of the project.
The plan of work will be posted on the ALFALFA website and other ALFALFA
group members informed. Any member of the group interested in the project
should feel free to contact the provisional project leader and propose to join,
provided that a useful contribution can be made within the given timetable.
The ultimate constitution of the team is however up to the project leader.
Progress reports will be required; continuation of project leadership will be
linked to consistency with the proposed schedule.
Posted projects, especially PhD thesis projects, will thus be "protected"
within the collaboration, and external users of the data will be advised of
the ongoing internal activities of the group.
0.1     In case of partial conflict of interests
between different proposed
projects, differences will be preferentially resolved amicably by team members.
The OC can act as arbitrator if required.
0.2     In preparation of publication of ALFALFA
and ALFALFA-related results by
group members, an authorship list should be sent to the OC. The OC may
thus advise or recommend modifications, for increased fairness.
0.3     One category of group members should be
considered potential co-authors
on all ALFALFA and ALFALFA-related results: that of individuals who :
0.4     In the publication of strictly ALFALFA HI data,
results or catalogs, the
authorship list will include those in 0.3. Inclusion of any others is up to
the consideration of the team leader.
0.5     For a paper that uses publicly posted but
data, such as source lists, level 1 or level 2 data sets, the same
considerations described above apply, if the initiators are ALFALFA
0.6     For a paper that uses published ALFALFA data, the usual criteria
of professional courtesy apply.
0.7     For all publications, an effort should be
made to protect the projects
led by PhD students, and to emphasize their contributions. For the papers
which are a substantive part of students' theses, "dilution" of credit
should be minimized, i.e. members of the collaboration who didn't
make a substantive contribution to that specific project should be
encouraged to exclude themselves from authorship.
0.8     "Surprise" or "unexpected" discovery reports: "Hot" sources will
occasionally be found during various stages of data inspection.
The discoverer will have the option of first authorship after
clearance with the OC, whether the finding is the result of blind
luck or planned search. Discovery papers of "hot" sources found
through automated signal identification algorithms will be led
by authors selected with a "merit" criterion that involves level of
commitment to observations, data processing, software development
and other overall contributions to the survey.
- (a) acted for more than 100 hours of telescope time as "designated observers",
within the last year
- (b) processed and inspected more than 100 hours of telescope time worth of data,
within the last year
- (c) made major contributions to the HI data processing and management software.
