5 Assume Floury map is in B1950 and Dinnat map is in J2000

6 Dinnat Map Transformed into the B1950 system

7 Floury Map assuming it was provided in B1950 system

8 Difference map reveals unexpected differences

9 Dinnat Map for Aquarius – Floury Map for SMOS Dinnat map HI line contribution is for 26 MHz Aquarius

10 Dinnat Map for SMOS – Floury Map for SMOS Dinnat map HI line contribution is for 19 MHz MIRAS

11 Dinnat Map for SMOS – Dinnat Map for Aquarius Shows impact of increased HI contribution for MIRAS
