Old 7" Baseray ratings

Does anyone have the output ratings of the old 7" baseray system? I can find the tables for the 9A but haven't been able to find it for the 7. If no tables does anyone have a multiplier they use to adjust from the 9A tables?
thanks for any help
Chris

    Thanks for the quick reply Stephen
    They show the SF/lin ft, is that the same as the steam rating (in SF) I see on the 9A table? If I compare 2.08 to the 9A ratings of 3.4 I get a ratio that the old 7" is 0.6 the rating of the 9A. My system is hot water, can I just multiply the BTU/Hr ratings in the 9A hot water table by that same ratio? Or is there something different about the steam rating that it can't be applied to the hot water ratings?
    Thanks again

    Hi Gents, anyone know what the water capacity (gallon/foot) is of 7" Base-Ray ? The 9 7/8” tall Base-Ray is 0.3 gal/foot, per the Installation Manual.

    My estimate of Volume of Water per Foot for 7" Base-Ray:
    given the 1" diameter of each internal pipe (or horizontal 'cylinder'; I measured it 5/22/2020), then the volume of a 1-foot 'cylinder' = Pi X r x r x height (or length in this case!) => 3.1416 x 0.5" x 0.5" x 12" = 9.4248 cubic inches = 0.04 gallon in each 'cylinder', so given 2 'cylinders' in each foot of Base-Ray =>0.08 gallon per foot of Base-Ray.
