The rights and responsibilities of Insight-HXMT core science team
Updated version, November 14, 2019

1. Insight-HXMT observations and scientific research programs

Similar to most of the astronomical space telescopes in the world, there are two major research programs for Insight-HXMT in-orbit observation, data analysis and associated research.

1) Insight -HXMT Core Science Program, which is the main subject of this document. Insight-HXMT Core Science Program aims at taking full advantages of Insight-HXMT with high cadence and long duration observations which may have strong international competitiveness and high scientific value. The Core Science Program is formulated by Insight-HXMT core science team members.
2) Insight-HXMT Guest Science Program, which is not covered by this current document. Insight-HXMT Guest Science Program is made of observations proposed by users or teams from both domestic and international astronomy communities, and selected by the dedicated review panel where users will be able to propose observations not already included in the Core Science Program.

This document does NOT cover HXMT data policy and results release.

2. The constitution of Insight-HXMT Core Science Team

The Insight-HXMT Core Science Team consists of the following three types of researchers:

1) Insight-HXMT team members, including the proposers of HXMT, members of HXMT payloads and HXMT Science Data Center (HSDC).
2) Domestic members, domestic key scientists who are interested in contributing to the Insight-HXMT scientific research.
3) International members, international scientists who have either made significant contributions to Insight-HXMT or recommended by cooperated organizations that contributed to Insight-HXMT.

A brief description of the responsibilities and rights of the three types of Insight-HXMT Core Science Team members is given below.

3. Insight-HXMT team members

Major responsibilities:

1) Complete the payload development and performance tests.
2) Study the space environment's impact on payload performance.
3) Participate in the payload calibration.
4) Participate in the HXMT in-orbit operation organized by HSDC.

Major rights:

1) Claim authorship in all scientific publications coming out of the Insight-HXMT Core Program observations during the data proprietary period. The order of authorship is classified in the Appendix.
2) Participate in/quit from any Core Science Group once approved by Insight-HXMT principal investigator (PI).

4. Domestic members

Domestic members are scientists who are the leading researchers in the related field and are interested in contributing to Insight-HXMT scientific research, and are divided into several Core Science Objectives Groups. Proposals for Insight-HXMT Core Science Objectives are solicited among domestic astronomy community, while the submitted proposals will be reviewed and selected by a peer review committee composed of domestic and international experts. The peer review committee determines the Core Science Objectives and the constitution of the corresponding proposal groups, as well as the observation time for each Core Science Objective. Subsequently, the Insight-HXMT HSDC will formulate the corresponding observation schedules for these Core Science Objectives.

Major responsibilities:

1) Justification of the Core Science Objectives, including scientific value, observation simulation, observation time estimation and observation schedule.
2) Complete the Insight-HXMT white papers for proposed objectives and publish it as key elements of the Insight-HXMT user manual or scientific publications.
3) Cooperate with HSDC on scheduling observations for the approved Core Science Objectives.
4) Accomplish the data analysis of the proposed Core Science Objectives in high quality and manage to publish the results.
5) The retrieved data can ONLY be accessed by authorized groups/members during the data proprietary period.
6) Collaboration with a third-party organization/scientist is ONLY allowed once permitted by a peer review committee or PI during the data proprietary period.
7) Apply all kinds of resources required to accomplish the requirements listed above, including funding and computation support.

Major rights:

1) Use the data from the Core Program observations during the data proprietary period, including possible collaboration with a third-party organization/scientist with an approval from a peer review committee or PI.
2) Participate in all kinds of major scientific research projects organized by PI, with funding support.
3) Apply scientific research projects based on Insight-HXMT Core Science Objectives, with funding support.

5. International members

International scientists who have made significant contributions to Insight-HXMT or been recommended from cooperation organizations can either apply to join a specific Insight-HXMT Core Science Group proposed by domestic members or submit new Insight-HXMT Core Science Objectives proposals to be reviewed by a peer review committee led by PI. The peer review committee will be in charge of the following review and approval. International members shall have the same rights as domestic Insight-HXMT core science members once the proposals approved by the peer review committee.

International collaborations are very welcome and foreseen to stipulate the application of Insight-HXMT. International scientists who haven NOT made direct contribution to Insight-HXMT are encouraged to participate in the collaboration groups of the Insight-HXMT Core Science Objectives. Application for collaborating with Insight-HXMT core science groups/members is required and shall be submit to the associated Core Science Group leader (the application forms are available online) and the PI. Once approved, they are allowed to access the data products during the proprietary period.

1. Insight-HXMT publication classification

Insight-HXMT publications are classified into four categories:
1) Instrument publications, namely type A publications, mainly report the Insight-HXMT scientific instruments, including HXMT science objectives, analysis techniques, in-orbit performance, calibration facilities, ground-based and in-orbit calibration, performance simulation (including instrument response and in-orbit background), model-based instrumental in-orbit performance and expected scientific results from simulations.
2) Data analysis publications, namely type B publications, report the scientific results from Insight-HXMT observations, including all types of Insight-HXMT observations and the joint observations with other telescopes.
3) Theoretical publications, namely type C publications, reports the theoretical results (testing or constraining theoretic models) using Insight-HXMT observation data during the data proprietary period, or using Insight-HXMT public observation analyzed by HXMT Core Science Team.
4) Joint publications, namely type D publications, is based primarily on data from other telescopes, but also uses Insight-HXMT observation data during the data proprietary period or Insight-HXMT public observation analyzed by HXMT Core Science Team.

2. Insight-HXMT publication level

Each of the four publication types is sorted into several levels

1) Type A publications
a) Level A1 publications, thematic publications of Insight-HXMT instrument, targeting at the design, principle, performance, sensitivity, calibration and expected results of Insight-HXMT instrument.
b) Level A2 publications, describes a single instrument or a set of instruments or HSDC.
c) Level A3 publications, any other instrument publications apart from level A1 and level A2 publications.


2) Type B publications
a) Level B1 publications, the first refereed scientific publication, a publication reporting the iconic and breakthrough results of Insight-HXMT, for instances, the first Nature publication (including Nature Series), the first Science publication, the first sky survey catalog publications and so on.
