Correction to "Lorentzian ion exosphere model"
V. Pierrard and J. Lemaire
In the paper "Lorentzian ion exosphere model" by V. Pierrard and J. Lemaire (Journal of Geophysical Research, 101(A4), 7923-7934, 1996) the real expres- sion of (28) or (39) is
(
rim noA• I'i; 1/2 W s I q- --
8
ß •'-2 1+•
n-1
(1) Identically, the real expression of (44) or (49) is
E(r) - rlmnoA•nl/•wS
8n -
n n-1•-
n-2-
w2n(n- 1))
(2)A problem can also occur when R + nw 2 < 0 in expressions (40) to (44). In this case, correct expres- sions are obtained by replacing in these expressions 1 + R/•w •, d, b • and f• by their norm and by replac-
ing (1- t) by (1- t). sign(•l + R/•w •) in (23) and
(24) i.e. the definitions of •(x) and •4(x) ßWe thank Nicole Meyer-Vernet for pointing out this error in the expressions of our model.
