Currently MakeCatalog's position-related columns are based on the average of all the pixel values. But in some scenarios, it good to have the position of the maximum pixel within each clump/object. |

With Commit 2e1deec6, MakeCatalog can now produce 6 more columns: the pixel positions of the minimum and maximum values in each object or clump through these options: '--minvx', '--maxvx', '--minvy', '--maxvy', '--minvz', '--maxvz'.
But I didn't have time to do the add columns for the respective coordiantes in WCS units (for example RA, Dec). But for the current purpose, this is enough. I am thus changing the title of the task to obtaining the same positions in WCS units )for doing later).
