*'''IPP Factor''': Intra/Inter Proposal Priority factor.  This will largely be of interest if you would like to prioritise different observations within your proposal; you would give a larger number to a higher priority observation.  Values must be between 0.5 and 2.  If you’re happy for all your observations to have equal priority, stick with the default value of 1.05.  This is a very basic summary, the full explanation of IPP can be found [https://lco.global/documents/20/the_new_priority_factor.pdf here].
