RMSNodeClass¶

class astroquery.solarsystem.pds.RMSNodeClass(url='', timeout=None)[source]¶

Bases: BaseQuery

a class for querying the PDS Ring-Moon Systems (RMS) Node ephemeris tools <https://pds-rings.seti.org/tools/>

Instantiate RMS Node query

Methods Summary

`ephemeris`(args, *kwargs)	Queries the service and returns a table object.
`ephemeris_async`(planet, *[, epoch, ...])	send query to Ring-Moon Systems Node server

Methods Documentation

ephemeris(*args, **kwargs)¶

Queries the service and returns a table object.

send query to Ring-Moon Systems Node server

Parameters:

planetstr: One of “Mars”, “Jupiter”, “Saturn”, “Uranus”, “Neptune”, or “Pluto”.
epochTime object, or str in format YYYY-MM-DD hh:mm, optional.: If str is provided then UTC is assumed. If no epoch is provided, the current time is used.
locationstr, or array-like, or EarthLocation, optional: If str, named observeratory supported by the RMS node, e.g. JWST. If array-like, observer’s location as a 3-element array of Earth longitude, latitude, altitude that istantiates an EarthLocation. Longitude and latitude should be anything that initializes an Angle object, and altitude should initialize an Quantity object (with units of length). If None, then the geofocus is used.
neptune_arcmodelint, optional.: which ephemeris to assume for Neptune’s ring arcs Must be one of 1, 2, or 3 (see https://pds-rings.seti.org/tools/viewer3_nep.shtml for details) has no effect if planet != ‘Neptune’
get_query_payloadboolean, optional: When set to True the method returns the HTTP request parameters as a dict, default: False
cacheboolean, optional: When set to True the method caches the download, default: True

Returns:

tableA Table object.
