... To derive the motion of a penny dropped inside an airliner moving at 600 miles/hr (about 1000 km/hr)--should we calculate it with respect to the interior of the airliner, or with respect to the ground? ...

Each such choice is known as a frame of reference . Some possible frames are -- the interior of the airliner, . ...

... The derivation of the reference multiplet is carried out in one of two basic styles: an `internal' style in which a kind of average multiplet is calculated from the values in the image themselves, without reference to any other information, or a `black body' (bb) style in which the reference multiplet is calculated using the widths of the energy bands (in the case of EPIC images) or the filter bandpasses (in the case of the OM). ...
