... Diameters computed with the following routines exclude super giants and binaries! If you want to bypass the latter restriction, set the BFLAG field to '.' (it is set to 'B' for binaries). The routine computing the diameter from (B-V) also excludes bright giants and stars later than K. diameter_ri Compute diameter from color index and -magnitude. diameter_bv Compute diameter from color index and -magnitude.
