While the temperatures they give in the tables are different than would normally be used in solar applications, they do provide some adjustment factors for other temperatures.
The tables are done for Twater in = 180F, Tair in = 60F. It appears to be pretty close to adjust the table heat transfer by (Tw - Ta)/120F, where Tw is your water in temp and Ta is your air in temp. This can be used to get a rough idea for values not covered in the correction table.
