<DT><STRONG>NOTES:</STRONG>
<DD><DL COMPACT>
<DT>1.
<DD>Station identifiers C may be up to 10 characters long,
and station names NAME may be up to 40 characters long.
<DT>2.
<DD>C and N are <I>alternative</I> ways of specifying the observing
station. The C option, which is the most generally useful,
may be selected by specifying an N value of zero or less.
If N is 1 or more, the parameters of the Nth station
in the currently supported list are interrogated, and
the station identifier C is returned as well as NAME, W,
P and H.
<DT>3.
<DD>If the station parameters are not available, either because
the station identifier C is not recognized, or because an
N value greater than the number of stations supported is
given, a name of `?' is returned and W, P and H are left in
their current states.
<DT>4.
<DD>Programs can obtain a list of all currently supported
stations by calling the routine repeatedly, with N=1,2,3...
When NAME=`?' is seen, the list of stations has been
exhausted. The stations at the time of writing are listed
below.
<DT>5.
<DD>Station numbers, identifiers, names and other details are
subject to change and should not be hardwired into
application programs.
<DT>6.
<DD>All station identifiers C are uppercase only; lower case
characters must be converted to uppercase by the calling
program. The station names returned may contain both upper-
and lowercase. All characters up to the first space are
checked; thus an abbreviated ID will return the parameters
for the first station in the list which matches the
abbreviation supplied, and no station in the list will ever
contain embedded spaces. C must not have leading spaces.
<DT>7.
<DD>IMPORTANT - BEWARE OF THE LONGITUDE SIGN CONVENTION. The
longitude returned by sla_OBS is
<B>west-positive</B>, following the pre-1984 <I>Astronomical
Almanac</I>. However, this sign convention is left-handed and is
the opposite of the one now used; elsewhere in
SLALIB the preferable east-positive convention is used. In
particular, note that for use in sla_AOP, sla_AOPPA and
sla_OAP the sign of the longitude must be reversed.
<DT>8.
<DD>Users are urged to inform the author of any improvements
they would like to see made. For example:
<UL>
<LI> typographical corrections
<LI> more accurate parameters
<LI> better station identifiers or names
<LI> additional stations
</UL></DL>
