function markpos
Mark positions using ds9. The positions are returned as a 2xn matrix, where n denotes the number of positions marked. Pressing the key 'q' will quit marking positions. When typing numbers between 1 and 9 the values are stored at that specific position. This way values can be overwritten. (Use ds9 v5.2 or newer!)

radius: | Optional, the radius around which the brightest pixel is searched for using centroid-method. |
