These are not available in phd1, In phd2, there are settings that define your pixel size and focal length. Then the graph has a button that changes the scale between arcseconds per pixel and pixels.
This is what I was getting at, if you use phd1 and have been using a guidescope the graph that you are used to has been hiding errors that you will begin to see if you use a longer focal length guider (namely OAG), or move to PHD2 which shows arc seconds per pixel. For this reason I think that people believe OAGs are inferior (guide star jumps around a lot), when in actual fact the graph is just scaled differently.
