Abstract (from CDS):

Coronal emission lines, especially the [Fe X]λ6374 line, are now being used as tracers for intermediate mass black holes (IMBHs) in low-mass galaxies. We show that the recent discovery of [Fe X]λ6374 emission in the metal-poor starburst SDSS J094401.87-003832.1 by Reefe et al. is, in fact, a misidentified line. The line interpreted as [Fe X]λ6374 is Si IIλ6371. We caution that current and future campaigns hunting for IMBHs with the [Fe X]λ6374 line need to account for possible contamination by Si IIλ6371 emission.
