Hello,
I tried downloading this FITS file and opening it with various tools.
It looks like a potential bug of the FITS viewer tool, and not an error in the data file itself. For example, fv is not interpreting correctly the header information. If you open the same FITS file with TOPCAT, the two column values are correct.
The FITS standard (see p.20) (https://fits.gsfc.nasa.gov/standard40/fits_standard40aa-le.pdf) states that "It is strongly recommended that every field of the table be assigned a unique, case-insensitive name with this keyword". So the following description, even if not recommended, is not forbidden :
TTYPE18 = 'b_logMBH' / [1/10]? Lower limit of logMBH
TTYPE19 = 'B_logMBH' / [3/11]? Upper limit of logMBH
TOPCAT interprets correctly the two columns and their values.
fv is treating them case-insensitive, and duplicates values of column 18 into column 19.
Most likely a bug to report to fv developers.
