We invite proposals for general observing time (GOT) and Large Program (LP) observations of EAVN. Please refer to the following KaVA and EAVN webpages for more details about the array and its performance, and how to prepare and submit a proposal.
This EAVN open-use call is based on risk-share, and provides opportunities of VLBI observations at 22 and 43 GHz for astronomers in the world.
We support astronomers in preparation of proposals, scheduling of your observations, and data analysis. If proposers are not familiar with EAVN, they are recommended to include at least one collaborator from EAVN (VERA, KVN, and Tianma). The contact address for the support is email@example.com.
EAVN observations are conducted with single polarization (LHCP) and the data are recorded with the data rate of 1 Gbps. NRO45’s data are recorded with the data rate of 2 Gbps and reformatted to 1 Gbps data. The total observation time for EAVN is up to 100 hours, while NRO45 is limited up to 50 hours. In addition, NSRT26 is available at only 22 GHz and EAVN proposers are asked to set an observation duration of no shorter than 6 hours per epoch if NSRT26 is included in your EAVN observations. Therefore, TMRT65, NSRT26, and NRO45 will participate in EAVN observations together with KaVA according to scientiﬁc needs and their availability. Note that proposals submitted to EAVN can be assigned to KaVA according to the decision by the KaVA/EAVN Time Allocation Commttee (TAC).
In 2019A semester, EAVN accepts a request of usage of sub-array conﬁguration (KaVA 7 telescopes and one or two telescopes from NRO45, TMRT65, and NSRT26), as well as EAVN full array conﬁguration with 10 or 9 telescopes at 22 or 43 GHz, respectively. A proposer shall clarify the reason for the choice of sub-array conﬁguration in the proposal.
The maximum request time per proposal is limited to 24 hours for EAVN. EAVN observations will be scheduled between 15th January 2019 and 15th June 2019, while NRO45 will be available until 15th May 2019 due to availability of the telescope.
The deadline of submission is at 08:00 UT on 1st November, 2018. Detailed information on the EAVN call-for-proposal can be found in the following webpage:
