SORA: Stellar Occultation Reduction and Analysis


Using and Citing SORA

Citing

SORA is a free software, and we kindly ask users that make use of it (or of part of it), especially in projects that results in scientific publications, to include the following citation:

Gomes-Júnior et al. (2022). SORA: Stellar occultation reduction and analysis.
MNRAS, Volume 511, Issue 1, March 2022, Pages 1167–1181
DOI: 10.1093/mnras/stac032

The scientific documentation of SORA is described in the paper available on Monthly Notices of the Royal Astronomical Society, which can be accessed on the following links:

Also, for a scientific publication, please be attentive the following terms of use for co-authorship:

  1. If you participate in the collaboration Rio/Granada/Paris and use SORA for the analysis of objects within the collaboration (e.g. TNOs, Centaurs, giant planets Trojans, among others), the SORA team may have the possibility to decide if any of its PIs should be co-author of the publication. In this case, the SORA team will commit to:

    • Teach the functionalities of the SORA package in a hands-on session or individually;

    • Run SORA, if necessary;

    • Fix any bug - in SORA code - with urgency;

    • Implement new requested features with high priority.

  2. If you participate in the collaboration Rio/Granada/Paris and use SORA for the analysis of objects outside the collaboration (e.g. Main-Belt Asteroids, NEAs, among others), the SORA team will not demand the possibility to become a co-author, but the code should be properly cited as stated above.

  3. If you are NOT from the Rio/Granada/Paris collaboration and use SORA for the analysis of any object, the SORA team will not demand the possibility to become a co-author, but the code should be properly cited as stated above.

As a drawback for itens 2 and 3, the SORA team will NOT commit to:

  • Teach the functionalities of the SORA package in a hands-on session or individually;

  • Run SORA;

  • Fix any bug - in SORA code - with urgency, unless it is a critical bug;

  • Implement new requested features with high priority;

In the event of granting priority or special attention to the user by the SORA team, further discussions will be made to address the addition of a specific co-author (or co-authors) from the team in the publication.
