Perret, Sandia Corporation Techni- cal Memorandum, Ref. Symbol 1922-2-(23) January 2, 1954. #* All crater radii are measured at original ground level. a Due to scour from water rushing back in, and ta aging (for GREENHOUSE) measured diameters may be large by 10 tq 30 per cent, mea- sured apparent crater depths may be shallow by‘a facter of 2 or more. b In Memorandum SWPEF 2/924 (354.2) dated 26 November 1954, the state- _ ment is made that plotting the IVY Mike data on an:‘expanded vertical scale gives a value for crater radius of 2800 ft (A=il. 02). 60
