Issue with kaguyasp2ascii Tool: "Not a Valid Kaguya Spectral Profiler File" Error

[HChristopher25]

I am encountering an issue with the kaguyasp2ascii tool. When attempting to convert a Kaguya Spectral Profiler file (.spc) to ASCII format, I receive the following error message:

(isis) hephzy@ipsec-10-2-193-58 ~ % kaguyasp2ascii from=/Users/hephzy/Downloads/SP_2C_03_00295_N148_E2403.spc to=/Users/hephzy/Downloads/SP_2C_03_00295_N148_E2403.txt
USER ERROR Input file [/Users/hephzy/Downloads/SP_2C_03_00295_N148_E2403.spc] is not a valid Kaguya Spectral Profiler file.

I have confirmed that the file was downloaded from JAXA’s data archive and should be a valid Kaguya Spectral Profiler file. This error occurs on both Mac and Windows systems.
