A generic get command..

Command> ?

get DSS.ESO(DSS2) NGC1055;get VizieR(USNO-B1) NGC1055;get SDSSDR3cat NGC1055 10';

Command> ?

get DSS.ESO(DSS2) NGC1055;get VizieR(USNO-B1) NGC1055;get SDSSDR3cat NGC1055 10';

- give access to all VO resource (via GLU registry)

- manage query parameters


Processing commands…

Command> ?

xmatch USNO-B1 SDSS;export XMatch* votableResult.xml votable;

Command> ?

xmatch USNO-B1 SDSS;export XMatch* votableResult.xml votable;

- CrossMatch by position

- Save result in VOTable


UCD manipulations…

Command> ?

filter pm { draw pm($[POS_EQ_PMRA], $[POS_EQ_PMDEC]) };

save imageResult.bmp;

Command> ?

filter pm { draw pm($[POS_EQ_PMRA], $[POS_EQ_PMDEC]) };

save imageResult.bmp;

- Draw arrows proportional to Xmatched object proper motion

- Save image and overlays


Multiview comparison…

filter brighter { $[PHOT*]< 17mag && (abs($[POS_EQ_PMRA])>3 || abs($[POS_EQ_PMDEC])>3) { draw } };

select A1 XMatch*;createROI 45";

filter brighter { $[PHOT*]< 17mag && (abs($[POS_EQ_PMRA])>3 || abs($[POS_EQ_PMDEC])>3) { draw } };

select A1 XMatch*;createROI 45";

modeview 9;

- Extract small images of selected objects

- Compare them with multiview mode
