2*+
3* Name:
4* palObs
5
6* Purpose:
7* Parameters of selected ground-based observing stations
8
9* Language:
10* Starlink ANSI C
11
12* Type of Module:
13* Library routine
14
15* Invocation:
16* int palObs( size_t n, const char * c,
17* char * ident, size_t identlen,
18* char * name, size_t namelen,
19* double * w, double * p, double * h );
20
21* Arguments:
22* n = size_t (Given)
23* Number specifying the observing station. If 0
24* the identifier in "c" is used to determine the
25* observing station to use.
26* c = const char * (Given)
27* Identifier specifying the observing station for
28* which the parameters should be returned. Only used
29* if n is 0. Can be NULL for n>0. Case insensitive.
30* ident = char * (Returned)
31* Identifier of the observing station selected. Will be
32* identical to "c" if n==0. Unchanged if "n" or "c"
33* do not match an observing station. Should be at least
34* 11 characters (including the trailing nul).
35* identlen = size_t (Given)
36* Size of the buffer "ident" including trailing nul.
37* name = char * (Returned)
38* Full name of the specified observing station. Contains "?"
39* if "n" or "c" did not correspond to a valid station. Should
40* be at least 41 characters (including the trailing nul).
41* w = double * (Returned)
42* Longitude (radians, West +ve). Unchanged if observing
43* station could not be identified.
44* p = double * (Returned)
45* Geodetic latitude (radians, North +ve). Unchanged if observing
46* station could not be identified.
47* h = double * (Returned)
48* Height above sea level (metres). Unchanged if observing
49* station could not be identified.
50
51* Returned Value:
52* palObs = int
53* 0 if an observing station was returned. -1 if no match was
54* found.
55
56* Description:
57* Station numbers, identifiers, names and other details are
58* subject to change and should not be hardwired into
59* application programs.
60*
61* All characters in "c" up to the first space are
62* checked; thus an abbreviated ID will return the parameters
63* for the first station in the list which matches the
64* abbreviation supplied, and no station in the list will ever
65* contain embedded spaces. "c" must not have leading spaces.
66*
67* IMPORTANT -- BEWARE OF THE LONGITUDE SIGN CONVENTION. The
68* longitude returned by palOBS (and SLA_OBS) is west-positive in accordance
69* with astronomical usage. However, this sign convention is
70* left-handed and is the opposite of the one used by geographers;
71* elsewhere in PAL the preferable east-positive convention is
72* used. In particular, note that for use in palAop, palAoppa
73* and palOap the sign of the longitude must be reversed.
74*
75* Users are urged to inform the author of any improvements
76* they would like to see made. For example:
77*
78* typographical corrections
79* more accurate parameters
80* better station identifiers or names
81* additional stations

85* PTW: Patrick T. Wallace

88
89* Notes:
90* - Differs from the SLA interface in that the output short name
91* is not the same variable as the input short name. This simplifies
92* consting. Additionally the size of the output buffers are now
93* specified in the API and a status integer is returned.
94
95* History:
96* 2012-03-06 (TIMJ):
97* Initial version containing entries from SLA/F as of 15 March 2002
98* with a 2008 tweak to the JCMT GPS position.
99* Adapted with permission from the Fortran SLALIB library.
100* 2014-04-08 (TIMJ):
101* Add APEX and NANTEN2
