While checking the size and mag of other Planetary Nebulae, I was told by the SIMBAD team that these objects contain NIR magnitudes of the stars, while the mid- and far-infrared, and the size were those of he nebulae. However, for M27 I'm seeing that the size is just 0.13 arcmin, while most sources set the size between 5 and 8 arcmin. Why is there this discrepancy? Is this an error or should I interpret this differently?
