Katdal has a few quirks when it can’t access data. You may end up with a dataset consisting of zeros only if the data is not available e.g. it is still on tape. We are currently working on improving error handling and logging. If your tarred MS is unexpectedly small, this may have happened to you. Please check on the status of the dataset and request restaging if it has been archived. There have recently been instances where downloaded measurement sets had scans fully flagged, yet the calibration report shows good solutions on these scans and no flags. We believe this occurs when the connection to the archive and the transfer servers times out due to network glitches. In this case, please refresh your browser and wait for the interface link to be recovered. Alternatively, contact the helpdesk to reset the file flags and have the conversion redonewith details to your observation. |
LTO 7 tape
Large projects can arrange with SARAO to have their data shipped on tape, at their own expense.
