In the 1984 paper where they introduced coefficients for the Tasselled Cap transformation of TM data, Crist and Cicone remarked, "As more experience is gained with TM data, adjustment of the TM Tasseled Cap coefficients may be indicated, leading to increasing precision in the data rotation." Have the coefficients they provided in Table 2 of that paper been updated? Is anyone using slightly different (or more precise?) coefficients than those in the table?
