Aladin V 3 script mode for the VO

Aladin V 3 script mode for the VO F. Ochsenbein, P. Fernique [CDS]

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

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

A generic get command. . Command> ? get DSS. ESO(DSS 2) NGC 1055; get Vizie. R(USNO-B 1) NGC 1055; get SDSSDR 3 cat NGC 1055 10'; - give access to all VO resource (via GLU registry) - manage query parameters F. Ochsenbein, P. Fernique [CDS]

Processing commands… Command> ? xmatch USNO-B 1 SDSS; export XMatch* votable. Result. xml votable; - Cross. Match by position - Save result in VOTable F. Ochsenbein, P. Fernique [CDS]

UCD manipulations… Command> ? filter pm { draw pm($[POS_EQ_PMRA], $[POS_EQ_PMDEC]) }; save image. Result. bmp; - Draw arrows proportional to Xmatched object proper motion - Save image and overlays F. Ochsenbein, P. Fernique [CDS]

Multiview comparison… filter brighter { $[PHOT*]< 17 mag && (abs($[POS_EQ_PMRA])>3 || abs($[POS_EQ_PMDEC])>3) { draw } }; select A 1 XMatch*; create. ROI 45"; modeview 9; - Extract small images of selected objects - Compare them with multiview mode F. Ochsenbein, P. Fernique [CDS]
