NAME
Astro::NED::Response::CoordExtinct - query results for a coordinates and extinction
SYNOPSIS
use Astro::NED::Response::CoordExtinct;
# create and initialize object
$obj = Astro::NED::Response::CoordExtinct->new( Field => $value, ... );
print $obj->Field;
# initialize existing object from an HTML response
$obj->parseHTML( $html );DESCRIPTION
An instance of Astro::NED::Response::CoordExtinct contains information returned by queries generated by Astro::NED::Query::CoordExtinct.
For complete information on the available fields, see http://nedwww.ipac.caltech.edu/help/calc_help.html.
Constructor
The constructor, new, takes a list of field, value pairs with which to initialize the object. See Fields for more information.
Non Accessor Methods
- dump
-
$obj->dump( $fh );Print a representation of the object to the passed filehandle. If no filehandle is specified, it is printed to the standard output stream.
- fields
-
@fields = $obj->fields; @fields = Astro::NED::Response::CoordExtinct->fields;This is either a class or an object method. As an object method, it returns a list of fields which had values in the object. As a class method, it returns a list of all possible fields.
- data
-
%data = $obj->data;This returns the object's data as a hash, keyed off of the field names. Use the accessor methods if possible.
- parseHTML
-
$obj->parseHTML( $html );Initializes the object from the passed HTML content. This is typically invoked only by Astro::NED::Query::CoordExtinct.
Accessing the data
Acesss to the data is via accessor methods named after the fields returned by NED (e.g. $obj->RA). They take no arguments and return the field values. Data can also be extracted into a hash via the data method.
Fields
The following fields are defined.
- Lat
-
The latitude of the object in degrees, if the output coordinate system is in latitude/longitude.
- Lon
-
The longitude of the object in degrees, if the output coordinate system is in latitude/longitude.
- RA
-
The Right Ascension of the object in degrees, if the output coordinate system is equatorial.
- Dec
-
The Declination of the object in degrees, if the output coordinate system is equatorial.
- PA
-
The position angle of the object in degrees, in the output coordinate system,
- U, B, V, R, I, J, H, K, L'
-
The extinction in the given bandpass.
- EB-V
-
The E(B-V) color excess.
EXPORT
None by default.
