GridFTP can be used without grid certificates via the sshftp url mechanism described below. Note that this uses ssh only to instigate the transfer between the two hosts - the data are then transferred using GridFTP and are not encrypted or otherwise handled by ssh so there is no performance penalty. text/html 2013-06-18T11:00:44+08:00 cormac http://cira.ivec.org/dokuwiki/doku.php/correlator/correlation?rev=1371524444&do=diff For DiFX1.5.* and higher. (Notes on the using the old CIRA-DiFX-1.0 are here if required) The basic steps in running the new version of DiFX are: * vex2difx - takes .v2d file as input and produces .input and .calc files (also .flag) * calcif2 - takes .calc file as input and produces model files (for DiFX 1.5 .uvw, .delay, [.rate, .im also produced]) * mpifxcorr - writes output files to .difx directory (as specified in input file) * difx2fits - converts output to FITS (and ascii tables … text/html 2013-06-17T10:14:11+08:00 tomrussell http://cira.ivec.org/dokuwiki/doku.php/outreach/start?rev=1371435251&do=diff If you organise or take part in any astronomy outreach activities, please add a brief description to this page so we can keep a record of what's going on. This makes writing reports for CIRA/ICRAR/Faculty/whoever, much easier. For record-keeping purposes, please also include an estimate of the size of the audience where known. Please also add any interviews, press releases or other contact with the media to this table. text/html 2013-06-13T14:28:19+08:00 laurastanford http://cira.ivec.org/dokuwiki/doku.php/correlator/geodetic?rev=1371104899&do=diff Geodetic observations require different post-processing to that of astronomy observations.
