TABLE Zone

Table to organize objects into declination zones

In order to speed up all-sky corss-correlations, this table organizes the PhotoObj into 0.5 arcmin zones, indexed by the zone number and ra.

name type length unit ucd description

zoneID int 4 EXTENSION_AREA id counts from -90 degrees == 0

ra float 8 deg POS_EQ_RA_MAIN ra of object

dec float 8 deg POS_EQ_DEC_MAIN declination of object

objID bigint 8 ID_CATALOG object ID

type smallint 2 CLASS_OBJECT object type (star, galaxy)

mode tinyint 1 CODE_MISC mode is primary, secondary, family, outside

cx float 8 POS_EQ_CART_X Cartesian x of the object

cy float 8 POS_EQ_CART_Y Cartesian y of the object

cz float 8 POS_EQ_CART_Z Cartesian z of the object

native tinyint 1 CODE_MISC true if obj is local, false if from the destination dataset
