datatype: double ucd: pos.cartesian.y;pos.bodyrc;pos.heliocentric/heliographic ?
xtype: utype: helio:location.y_cart
description: Position in arcsecs from centre of the sun.

name: duration
datatype: int ucd: time.duration
xtype: utype: helio:flare.duration
description: Duration of the flare in seconds
name: count_sec_peak
datatype: int ucd: phot.count
xtype: utype: helio:flare.magnitude.hard_xray_quantifier.hard_xray_count
description: Peak counts/second in energy range 12-25 keV, averaged over active collimators, including background.
name: total_count
datatype: int ucd: meta.number
xtype: utype: helio:flare.magnitude.hard_xray_quantifier.hard_xray_count

name: energy_kev
datatype: int ucd: phys.energy
xtype: utype: helio:flare.magnitude.hard_xray_quantifier.energy_keV
description: The highest energy band in which the flare was observed.
name: flare_number
datatype: int ucd: meta.id
xtype: utype: helio:flare.rhessi_flare_number
description: An ID number, ymmddnn, e.g., 2042101 is the first flare found for 21-Apr-2002. These numbers are not time ordered, e.g., flare 2042129 occurred before 2042104. Also all sorts of problems have been noted since 2010 has started, and the energy range has been changed, resulting in more than 100 flares in certain days. Flare_ids for 2010 and beyond start with a 2 digit year, and there can be 3 digits for the flare number in a given day e.g., 100601102.
