Work out the median seeing.
| ap | The current ap structure |
| nrows | The number rows in the object catalogue |
| ellipt | The array of ellipticities from the object catalogue |
| pkht | The array of peak heights from the object catalogue |
| areal | The array of areal profiles from the object catalogue |
| work | A work array (should probably allocate this local at some stage) |
| fwhm | The output FWHM estimate |
Description: The areal profiles for an array of objects is examined. The point where the areal profile falls to half its peak value is found for each object and the final seeing estimate is the median of these results
