Visualization tools such as Plan views, 3D views, time-based data views and session editors help you «see» the data in the context of the entire project. But MOC is used for describing sky coverage, and HiPS is used for accessing data (pixels, catalog sources…) 6.3 * Why do I have to use MOC rather than other coverage method? For instance «get SDSSDR7(Title=filter g,Number=5) NGC1055» will return the five first images matching the «Title» constraint. 7.6 * Can I define a script function? Aladin spends about 500 bytes per catalog object in memory. It means that you can load about 2 million objects catalog with 1 GB RAM free.But in practice, it is difficult to work with more than 1 million object due to the redrawing time. Force the reticle moving: with the CTRL key down, a click in the view (or one view in multiview mode) moves the reticle (large magenta cross) even if there are «selectable» graphical overlays at this position. 4.46 How to use the plane stack?
Only the displayed views use memory, the invisible views do not spend any memory. Yes you can ! You yave two methods: by creating a list of view centered on the objects, or via a script : 7.11.1 Thumbnail as a list of views The simplest method is to use a progressive survey and to generate as many views as you have targets. Use the Macro menu: File => Use selected plane sources as params». 7.10 Can I launch a «macro» via a script command? This solution is easy to use, fast but it is based on the 4 image corners positions — so it can have small distorsions.
Now, you can add some constraints in the get command list for filtering the metadata tree and immediately download the relevant image.For instance «get SDSSDR7(Title=filter g) NGC1055» will return immediately the first image for which the metadata title contains the «filter g» substring. Ser., 143, 33-40 (2000) — April(I) 2000. 10.3 What is SAMP? SAMP is a protocol for communication between client-side astronomy applications. Click on the «pixel» button and click on the «Reverse» button. 4.58 Can I display my color map? Target can be a Simbad identifier or J2000 coordinates in sexagesimal syntax (with a space as the separator). Radius must be specified with the unit (deg,arcmin,sec or ‘ «) without any blanks between the figure and the unit. Therefore, this type of survey is appropriate to measure user experience standards.Requirements to perform an Active Survey:● Two wireless network cards.
