The image appears to have been stripped out. Nevertheless, people (or
maybe just me?) tend not to want to type stuff in from an image, so if
you could provide the actual input commands, you would probably get
more help.
Without knowing what you're actually doing, perhaps you could do a
rudimentary uncertainty calculation using first order Taylor series
about the points of interest.
