On the day you will go to Haven, don't forget your bottle,
air is pretty thin up there !

1. refreshed/augmented [kPa], [rho]
2. augmented from latest Ralph Carmichael
3. added solve NASA(h)
4. by same token => Mach sub/supersonic.

... here is the missing link, NASA altitude vs kPa.
Two gorgeous segments from discrete NASA inverser
collected in the data inverse. Discrete solver included
as demo for other applications ... play with that one.

Revisit/resume km_kPa ... from several proposals:
1. Thiele two segments
2. Transmute modified Carlos
3. Wolf-Rabbit two segments
4. HKL [simple/corrected]
5. Exact_4 [± 0.001 m ... 0 m up ~ 11 km] <= ! ! !

Thanks Carlos, tested page 13.
The all range [0 .. 101.325 kPa] ... [0 .. 60km]
resumed in 4 segments of same format, zero error page 11, 12
NASA is short of accepting @ 60 km, pressure still exists !.

Tiele 13 terms converted to J continued fraction
