Skywalker: Seeing the sky through a telescope's eye
Size does matter:
These surveys have in common that they produce large contiguous high-resolution images, ranging in size from 3'x3' (UDF) to 1.4°x1.4° (COSMOS). These images are either difficult or impossible to be printed on paper or to be viewed as single images on a screen. As an example the COSMOS mosaic will sport more than 100.000 pixels on a side with corresponding file sizes, even in JPEG format.
We have recently published a PASP paper on the techniques behind the COSMOS Skywalker, and created a SourceForge.net project to access the COSMOS SkyWalker and pointers to helper tools.
