1 F.Ochsenbein, P. Fernique [CDS] Aladin V3 script mode for the VO

2 F.Ochsenbein, P. Fernique [CDS] Why a script mode ? An alternative to the graphical interface (ASCII console) An alternative to the graphical interface (ASCII console) A way to let other applications control Aladin : A way to let other applications control Aladin : For specifying the starting state (applet context) For specifying the starting state (applet context) For interfacing with other applications (VOPlot) For interfacing with other applications (VOPlot) For using Aladin as a "black-box" producing charts, images, postage stamp images... For using Aladin as a "black-box" producing charts, images, postage stamp images...

3 F.Ochsenbein, P. Fernique [CDS] Command > ? A script example step by step… In line help Console

4 F.Ochsenbein, P. Fernique [CDS] A generic get command.. Command> ? get DSS.ESO(DSS2) NGC1055; get VizieR(USNO-B1) NGC1055; get SDSSDR3cat NGC '; Command> ? get DSS.ESO(DSS2) NGC1055; get VizieR(USNO-B1) NGC1055; get SDSSDR3cat NGC '; - give access to all VO resource (via GLU registry) - manage query parameters

5 F.Ochsenbein, P. Fernique [CDS] 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

6 F.Ochsenbein, P. Fernique [CDS] 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

7 F.Ochsenbein, P. Fernique [CDS] Multiview comparison… filter brighter { $[PHOT*] 3 || abs($[POS_EQ_PMDEC])>3) { draw } }; select A1 XMatch*; createROI 45"; modeview 9; filter brighter { $[PHOT*] 3 || abs($[POS_EQ_PMDEC])>3) { draw } }; select A1 XMatch*; createROI 45"; modeview 9; - Extract small images of selected objects - Compare them with multiview mode

8 F.Ochsenbein, P. Fernique [CDS] Scripts in Web context aladin.pl? script=get+MyData(http://nedwww.ipac. caltech.edu/dss1B2/Bb/MESSIER_104.I.IIIaJ.dss1. fits.gz);sync;get+NED;get+VizieR(USNO2); get+VizieR(2MASS);get+VizieR(NVSS)
