14.4 ERROR MESSAGES
"Error in LOG data"
There are negative values for either frequency or resistivity for CSAMT, TDCSMT and
AMT only. It is difficult to get a negative frequency value, but the check is there. For
TEM we take the absolute value of the decay value.
"Zero range in data"
Applies to all programs. There are at least two data points available, but maximum_X -
minimum_X = 0, or maximum_Y - minimum_Y = 0.
"Insufficient/illegal data"
Applies to all programs. A minimum of two data points does not exist in the selected
data blocks.
"Data OK"
Applies to all programs. No problems were found with the data.
