    I have used Hyperion tools to convert L1R hyperion file. I used the scale factor file created in this process, unedited at the beginning of the Flaash conversion dialogue. I assume this is ok. I assume the header file mentioned in the hyperion tools guide is the header file created in the conversion process. Which are the bad bands in this text file? Are they the ones right at the bottom identified as bbl consisting of 0s & 1s? why does this header file need the band values replaced after flaash is applied? I have attached the text below: ENVI description = { ENVI File, Created [Mon Mar 19 18:01:29 2012]} samples = 256 lines = 7030 bands = 242 header offset = 0 file type = ENVI Standard data type = 2
