Fixed numerical mean budgets for nearby immersions in a linear phase chart. The chart, cut-off, coefficient form, and weighted two-jet profile are fixed before the nearby immersion and slow scale are supplied.

    Source documentation

    The numerical part of the local mean budgets, without the map or scale.

    Source documentation

    All seven mean-budget profiles can be chosen before a nearby immersion and its actual slow scale. The dependence on its two-jet is the displayed fixed profile H, rather than an implicit map-dependent constant.
