[OpenLayers-Users] My TileCache layer is off by scale and location

Ok - the calculation of the resolution is clearer now:

http://wiki.osgeo.org/index.php/WMS_Tiling_Client_Recommendation

says "Rather than rely on the much-overloaded concept of "scale," this
recommendation instead will describe scales or zoom levels in terms of
"resolution," defined in terms of map units (typically degrees or meters) per
pixel."

So, for a scale of 1:2000000 at a pixel size of 0.28mm I come up with a
resolution of 560. Correct?

Still I don't get a positionwise correct image, but after setting tilecache's
bbox to the same figures as OpenLayer's the image seems to be in a more scale.
