This is an erratum to ATel #17984.
Due to an error in our newly developed calibration software, the originally listed values of the degree of linear polarization (DoLP) are incorrect. The corrected values in the SLOAN r and i bands are as follows:
- Central coma: 0.045±0.003 (r) 0.068±0.005 (i)
- Narrow tail: 0.079±0.002 (r) 0.109±0.003 (i)
- Broad tail: 0.088±0.001 (r) 0.115±0.001 (i)
Accordingly, the DoLP of the central coma of 220P/McNaught in the SLOAN r band is comparable to the values around ~0.05 in the red continuum typically observed at the same phase angle (~37 degrees) for low-Pmax (Jupiter-family) comets (Kiselev et al., 2015, DOI:10.1017/CBO9781107358249.022).
Apologies for any inconveniences caused.
