• Targets passed are corrected for basic user input. 'wasp43b' is interpreted as 'WASP-43 b'. List must be of the form given in the example below.
• Initial checks for targets from the exoplanet archive are then taken to ascertain whether the prior data extracted has entries in all columns. If there are missing entries for a given target in the list, the user will be asked whether to proceed.
• All available split curves are fitted with TransitFit, then the results are then zipped up and time stamped. Optionally sends an email upon an error or full completion of a target.

Background tasks for feeding data to TransitFit include:

• Set the filter path to the TESS Filter.
• Download EU/NASA/ORG/OEC exoplanet archive data every 2 days (checks the file age).
• Download MAST lightcurve data for target TESS Sectors.
• Split the lightcurves into seperate transits or epochs.
• Create the data paths to each seperate epoch.
• Run TransitFit.
• Delete all downloaded data and inputs.
• Zip up and timestamp the output.
