10** Parameters of selected groundbased observing stations.
11**
12** Given:
13** n int number specifying observing station
14**
15** Either given or returned
16** *c char identifier specifying observing station
17**
18** Returned:
19** *name char name of specified observing station
20** *w double longitude (radians, West +ve)
21** *p double geodetic latitude (radians, North +ve)
22** *h double height above sea level (metres)
23**
24** Notes:
25**
26** Station identifiers may be up to 10 characters long
27** (plus string terminator), and station names may be up to
28** 40 characters long (plus string terminator). Leading or
29** trailing spaces are not supported.
30**
31** c and n are alternative ways of specifying the observing
32** station. The c option, which is the most generally useful,
33** may be selected by specifying an n value of zero or less.
34** If n is 1 or more, the parameters of the nth station
35** in the currently supported list are interrogated (n=1
36** meaning the first station in the list), and the station
37** identifier c is returned as well as name, w, p and h.
38**
39** If the station parameters are not available, either because
40** the station identifier c is not recognized, or because an
41** n value greater than the number of stations supported is
42** given, a name of "?" is returned and c, w, p and h are left
43** in their current states.
44**
45** Programs can obtain a list of all currently supported
46** stations by calling the routine repeatedly, with n=1,2,3...
47** When name="?" is seen, the list of stations has been
48** exhausted.
49**
50** Station numbers, identifiers, names and other details are
51** subject to change and should not be hardwired into
52** application programs.
53**
54** All station identifiers c are uppercase only; lowercase
55** characters must be converted to uppercase by the calling
56** program. The station names returned may contain both upper-
57** and lowercase. All characters up to the first space are
58** checked; thus an abbreviated ID will return the parameters
59** for the first station in the list which matches the
60** abbreviation supplied, and no station in the list will ever
61** contain embedded spaces. c must not have leading spaces.
62**
63** IMPORTANT -- BEWARE OF THE LONGITUDE SIGN CONVENTION. The
64** longitude returned by slaObs is west-positive in accordance
65** with astronomical usage. However, this sign convention is
66** left-handed and is the opposite of the one used by geographers;
67** elsewhere in slalib the preferable east-positive convention is
68** used. In particular, note that for use in slaAop, slaAoppa
69** and slaOap the sign of the longitude must be reversed.
70**
71** Users are urged to inform the author of any improvements
72** they would like to see made. For example:
73**
74** typographical corrections
75** more accurate parameters
76** better station identifiers or names
77** additional stations
