| 7 | | Our scripts require that data be named according to the standard convention e.g. OWL219b-14-1, where 219 is the julian day, b the sortie, 14 the year and 1 the flightline. If this is not the case, you must rename both the files and the directories. renameOwl.py can be run with -p specifying the project directory. You will need to set write permissions for all the raw directories and files to do this; taking a backup is strongly recommended. |

The files should have been renamed during unpacking, but if this is not the case, run proj_tidy.sh -e -p <project directory> to generate the move commands. Check that every move command is present before executing, as partial renaming cannot be completed in a second run. Taking a backup of the data files is recommended before renaming. |

| | 11 | The radiometric calibration will fail if the dark frames are saved in a separate file to the data (Ops sometimes do this). Check the capture directory for any extra files labelled like they might be dark frames and append them to the end of the data file. Remember to add the autodarkstartline key to the header file. Alternatively use the script stitchOwl.py. |
| 39 | | Geocorrection is conducted in the same way as for fenix data, using APL. Generate a config file using generate_apl_config.py -o processing/owl/o2014219b.cfg (make sure it begins with an '''o''')to keep processing separate from fenix. Currently you need to add the boresight values to the config file (owl_boresight = 0.12 -0.32 0.32). You may want to delete or set to false the fenix lines if only processing owl data. Make sure the project directory structure is complete (same as fenix). Submit to the grid using specim_qsub.py <config_file> and calculate the SCTs. Once you have done this you can generate the mapped data (102 bands) by setting owl_bandlist = ALL and setting the SCT value for each line. |

| | 49 | Early owl files have corrupt nav files, so if you get this message in the log or 'Requested sync time index is out of bounds in GetSyncDelay()' set the config file to use_nav = false. |

| | 51 | If there appears to be stripping across the mapped files, bright and dark lines, or sections of a flight line don't match up the sensor has probably dropped frames. These can be checked in the .log file in the capture directory. These empty lines need to be inserted into the level 1b data file before geocorrection to map the flight line correctly. |
