Change in Russian Federation data rights

13 January 2016

Last year, the Russian Advisory Committee (RAC) for INTEGRAL agreed with proposed changes to the data rights policy with regard to Russian Federation proposals in AO-13. Data or science rights to the targets or science in the field of view (FOV) of the instruments proposed by the PIs from the Russian Federation and accepted by the TAC will be allocated to these PIs with the usual 1-year proprietary period. However, the rest of the field will be made public to the community at-large through the consolidated data programme, i.e., having a policy similar to that for non-Russian Federation proposals. Russian PIs still have exceptional access to the near-real time data of their observations. This policy change is in effect from January 1. Note that the guaranteed return to the Russian science community from the open time programme stays 25%.

Prior AOs

The observing schedules and lists of approved targets for AO-1 to AO-16 are available from ESA's INTEGRAL web site. The AO-1 through AO-16 observing targets are also listed in the INTEGRAL Observing Program Catalog (INTEGRALAO) in the HEASARC INTEGRAL archive. It is searchable using either Browse or Xamin.
