leda-aladin v 0.6 (2002/04/18)
This CGI process a coordinate-box request to LEDA, /leda

Usage:
#/cgi-bin/leda-aladin.cgi?ra=$1&de=$2&width=$3&height=$4&name=$5&type=$6&constraint=$7

$1: (ra) Right ascension J2000 in [deg]
$2: (de) Declination J2000 in [deg]
$3: (width) Width of the box [arcmin]
$4: (height) Height of the box [arcmin]
$5: (name) Designation of an object in LEDA
$6: (type) Type of request
$7: (constraint) Additional constraints (LEDA SQL where clause)

If (type)="glu" is given, return the glu records for Aladin corresponding
to the other requests. If (type)="astrores", return an astrores document.
Otherwise display an help text

If (name) is defined, perform a search around the corresponding object and
ignore parameters (ra), (de).

If none of (name), (ra), (de) and (width) is defined but (constraint) is
defined, perform a whole sky search with (constraint). Note that if
(constraint) is a blank or null string the request will return the whole
database. Using SQL constraints require an advanced knowledge of LEDA (see
documentation).

Otherwise perform a search near position.

(For a positional search, if any of (ra), (de) or (width) is undefined, or
if an error occurs in the query, eg. syntax error in (constraint), the search
will return 0 record... I do not know how to pass an explicit message)

If (height) is omitted it is defaulted to (width).

Examples:
/cgi-bin/leda-aladin.cgi?type=astrores&ra=187.70&de=12.39&width=30&height=30
/cgi-bin/leda-aladin.cgi?type=astrores&name=M87&width=30&height=30
/cgi-bin/leda-aladin.cgi?type=astrores&name=M87&width=30&height=30&constraint=v+<+3000
/cgi-bin/leda-aladin.cgi?type=glu
