For the accepted proposals, users are requested to prepare the observing schedule file, at least one week before the observation. The observer who is not familiar with KaVA system is recommended to consult with KaVA user support team (email@example.com) to prepare schedules. KaVA operation & support members take full responsibility for observation and correlation process.
The users are asked to submit a VEX file two weeks before the observation to firstname.lastname@example.org. Observations will be performed by KaVA operators so that users will not be asked to take part in observations.
The correlation process will be carried out by Daejeon correlator at KJCC (Korea-Japan Correlation Center). The correlated data can be downloadable via FTP and its address will be given to the PI via email. Then, users are asked to examine the correlated data and if there is some problem, you can request re-correlation within a month after the correlation. In this case, you should provide the details of your problem clearly. In principle, the raw data used for observations will be recycled one month after the correlation.
The PIs will have exclusive access to the data obtained for 18 months after the correlation. This policy is applied to each observation, even if the proposal comprises multi epoch observations. After this exclusive period, the data will be publicly accessible.
You can download the KaVA VEX example file from here and modify them for your observation. More sample vex files for a specific observation case are also available in the following table. The schedule submission should be done by a standalone vex file including calibration procedures (e.g. sky dipping, hot/cold calibration, focusing, pointing etc.). The correlation parameters must be clearly specified as an example VEX file.

At present, following observing modes are available. Please refer to the KaVA status report for more details.
Following items are the check list for the success of VLBI observation.
