East Asian VLBI Network (EAVN)

Data Reduction

For the KaVA/EAVN data reduction, the users are encouraged to reduce the data using the NRAO AIPS software package. The observation data and calibration data will be provided to the users in a format which AIPS can read.

As for the amplitude calibration, we will provide "ANTAB" files which include the system temperature information measured by the R-sky method and the information of the dependence of aperture efficiency on antenna elevation. If the user wants weather information, the information of the temperature, pressure, and humidity during the observation can be provided.

At present, both KaVA and EAVN do not support for astrometric observations. In case of questions or problems, the users are encouraged to ask the contact person in KaVA/EAVN members and/or the assigned support scientist for supports.
