IDL> print,CV_Coord(FROM_RECT=replicate(!values.F_NAN,3),/TO_SPHE RE)
0.000000 0.000000 NaN
Should not the result rather be (NaN,NaN,NaN) ?

Right.
Except if you want to plot those angles (for example, a map in longitude and latitude). As usually in IDL, NAN data values would be unplotted. Here you get an extra point in (0,0).
