JVN system is still being developped and
some capabilities are remain to be implemented.
This call for proposals is intended for people who are willing and able to make use
of data obtained in this potentially difficult environment.
Therefore, JVN observing time is currently restricted to researchers and students who are related to the JVN project only. The JVN steering committee expects a PI to play a leading role in the proposed observations.
- Proposal format
- Each proposal should consist of a cover sheet and an attached main part, and must be written in Japanese or English. Template of JVN proposal cover sheet is available (Word, PDF).
- The main part of the proposal should include a full scientific justification and technical justification. The main part is limited to a maximum of two A4 sized pages of text (11pt or larger) plus two A4 sized page of figures, tables, and references.
- Submitted proposals must be formatted in PDF. Please convert your cover sheet and main part files into PDF before submission.
- Destination for submission
We accept proposal sumission via e-mail. Submit your PDF files of the coversheet and the main part to Kenta Fujisawa.
The JVN proposal deadlines are March 31, July 31, and November 30 of each year.
- Time allocation
- Making a schedule file
- Data reduction
Most proposals are queue scheduled to maximize return based on the instrument status and availability for the JVN antennas.
PIs of accepted proposals should prepare to create observation schedules. JVN accepts a DRG format schedule file as an output of PC-SCHED program. Documentation of PC-SCHED in the EVN site is available here. People who are not familiar with PC-SCHED are urgued to consult Kenta Fujisawa.
The Mitaka VLBI correlator at NAOJ is used for correlation. The correlated data in the FITS format is shipped to PIs via DVD disks.
The initial reduction and calibration of JVN data is performed with AIPS. Difmap is also used for imaging and self calibration. People who are not familiar with VLBI data reduction are urgued to consult Kenta Fujisawa.
