| CGI parameters: |
| spatial |
Required |
Type of spatial query: Cone, Box, Polygon, and NONE |
| |
|
polygon
|
Convex polygon of ra dec pairs, separated by comma(,)
Required if spatial=polygon
|
| radius |
Cone search radius
Optional if spatial=Cone, otherwise ignore it
(default 10 arcsec).
|
|
radunits |
Units of a Cone search: arcsec, arcmin, deg.
Optional if spatial=Cone (default= arcsec)
|
|
size |
Width of a box in arcsec
Required if spatial=Box.
|
|
objstr |
Target name or coordinate of the center of a spatial search
center.
Target names must be resolved by SIMBAD or NED.
Required only when spatial=Cone or spatial=Box.
Examples:
M31, 00 42 44.3 -41 16 08,
00h42m44.3s -41d16m08s
Note:
Note: The target name or position must be URL encoded.
Simple way is to replac a space, " ", with plus, "+":
e.g., 00 42 44.3 -41 16 08, 00h42m44.3s -41d16m08s
is decoded as
00+42+44.3+-41+16+08, 00h42m44.3s+-41d16m08s

URL Examples:
The following examples demonstrate program interfaces
that return an ASCII table (outfmt=1)
from the 2MASS All-Sky Point Source Catalog with different formats of an input
object name or position. To use these program interfaces with wget, run commands
of the form
wget "[example url]" -O outfile.tbl
where [example url] is one of the following examples and outfile.tbl
is the desired output filename. For more details, see the Program Interface Guide.
