FDEG  int  Degrees of freedom of Chebychev polynomials  

NITER  int  The number of iterations during solving  

object_id  oidtype  The object identifier
The object identifier is an attribute shared by all persistent instances. It is the prime key, by which object identity is established

THRESHFRAC  float  The fraction of the maximum threshold below which the iteration is allowed to threshold  

VERBOSE  str  Verbosity level (NONE, NORMAL, VERBOSE, DEBUG)  

XMAX  float  Maximum Xcoordinate of useful pixel plane  

XMIN  float  Minimum Xcoordinate of useful pixel plane  

XPIXSIZE  float  The scaling of pixels with which CDELT1 is multiplied  

YMAX  float  Maximum Ycoordinate of useful pixel plane  

YMIN  float  Minimum Ycoordinate of useful pixel plane
