FUNCTION fGetNearbySpecObjXYZ

Returns table of scienceprimary spectrum objects within @r arcmins of an xyz point (@nx,@ny, @nz).

There is no limit on the number of objects returned, but there are about 40 per sq arcmin.
returned table:
specObjID bigint, -- Photo primary object identifier
run int NOT NULL, -- run that observed this object
camcol int NOT NULL, -- camera column that observed the object
field int NOT NULL, -- field that had the object
rerun int NOT NULL, -- computer processing run that discovered the object
type int NOT NULL, -- type of the object (3=Galaxy, 6= star, see PhotoType in DBconstants)
mode tinyint NOT NULL, -- mode of photoObj
cx float NOT NULL, -- x,y,z of unit vector to this object
cy float NOT NULL,
cz float NOT NULL,
htmID bigint, -- Hierarchical Trangular Mesh id of this object
distance float -- distance in arc minutes to this object from the ra,dec.
Sample call to find SpecObj within 5 arcminutes of xyz -.0996,-.1,0
select * from dbo.fGetNearbySpecObjXYZ(-.996,-.1,0,5)
