Table 2

Values for the parameters in EWS used for the reduction of the MIDI data of the Circinus galaxy.

Parameter Value Description

smooth =10 frames width of boxcar for high pass filtering
gsmooth1 =0.36 s 1st pass: coherent smoothing
asmooth1 =2.00 s 1st pass: amplitude smoothinga
msmooth1 =4.00 s 1st pass: median smoothing
gsmooth2 =0.36 s 2nd pass: coherent integration length
msmooth2 =1.00 s 2nd pass: median smoothing
ngrad =2 2nd pass: 2 ngrad + 1 = 5 delay rate fits
maxopd1 =40 μm 2nd pass: maximum search OPD
psmooth =0.18 s smoothing for phase estimation
pgrad =0 2 pgrad + 1 = 1 linear phase rate fit
maxopd2 =100 μm flagging: maximum allowed OPD
minopd =0 μm flagging: minimum allowed OPD
jumpopd =10 μm flagging: maximum jump in delays
jitteropd =1.5 μm flagging: maximum jitter in delays

Notes.

(a)

Using a Gaussian instead of the default boxcar smoothing.
