EVN data analysis

How did your experiment go? The EVN Feedback Pages are an archive of brief reports posted by staff at the EVN telescopes.
• Data analysis will require the downloading of various files (e.g. .antab, .uvflg) from the EVN vlbeer archive in Bologna.
• All EVN user experiments are now automatically pipelined by JIVE support scientists. Users can peruse the pipeline output (postscript plots) and can also use the AIPS calibration tables produced.
• An EVN data reduction guide is now available (html, postscript).
• The initial reduction and calibration of EVN data is performed with AIPS (home, cookbook).
• Martin Shepherd's Difmap program can also be used for imaging and self-calibration of EVN data.
• The performance of the telescopes during an experiment can be compared to that expected as tabulated in the EVN status table.
• The positions of EVN telescopes used by the EVN correlator were updated towards the end of April 2002 and data correlated before this can be corrected.
