Getting from USNOB to PPMXL Prerequisites: * 2MASS in twomass.data (gavoimp 2mass/res/2mass data) * PPMX in ppmx.data (gavoimp ppmx/res/ppmx) * The usno data and the usno plate data (sigh). Assume we're in inputs/usnob/res Import usnob: gavoimp usnob data Import usnob plate data gavoimp usnob platedata Prepare PPMX crossmatch gavoimp usnob usnobPPMX Prepare 2MASS crossmatch (will be needed later) gavoimp usnob usnob2MASS Compute per-field corrections from PPMX crossmatch: gavoimp usnob platecorrs Dump all data necessary for Least Squarse Fitting bin/dumppmxcross.py bin/dump2masscross.py cd bin python setup.py build python dumpobspos.py cd .. Merge all the dumps bin/mergeDumps.sh Send off /var/svn/space_for_gavo/dumps/dump.gz to Röser (TODO: obtain the source he used) With the result of his program, do as described in PPMXL.
