There is a problem in the electronic version of the
LEHPM
catalog with the columns
pmRA
and
pmDE
(these columns are not included in the printed sample of the paper). The values of these columns should be:
pmRA
=
pm
* sin(
pmPA
)
pmDE
=
pm
* cos(
pmPA
)
but the values given in the catalog may differ widely from these for stars south of -80°. An extreme example is
LEHPM 2-2058
for which the vector (
pmRA
,
pmDE
)=
(0.1778,0.1677)
is almost the opposite of the vector given by its polar components (
pm
,
pmPA
)=(0.2445,225.05) resulting in (
pmra
,
pmDE
)=
(-0.1730,-0.1727)
