Table 1:

Overview of the processing parameters for the three data sets that are handled with SPAM as defined in the test cases.
Field name VLSS J0900+398 (simulated) VLSS J0900+398 (real) VLSS J1300-208 (real)
Pixel sizea 18.9 $^{\prime \prime }$ 18.9 $^{\prime \prime }$ 11.1 $^{\prime \prime }$
Number of facets 347 243 576
Facet separation $1.18^{\circ}$ $1.18^{\circ}$ $0.62^{\circ}$
SPAM calibration cyclesb 1 1 3
Peeling sources 10c 11 9
KL model height 1000 kmd 200 km 200 km
Fitted KL model terms 15 15 20e
Rejected time intervals 0 / 464 25 / 464 86 / 484
Model fit phase rms $3.0^{\circ}\pm 0.8^{\circ}$ $21.3^{\circ}\pm 2.4^{\circ}$ $23.2^{\circ}\pm 3.2^{\circ}$
Peeling corrections applied directly no yes yes
a The pixel size for all field-based calibration images is 20 $^{\prime \prime }$. b Adding more cycles did not significantly improve the image quality. c Arbitrarily limited to mimic a more realistic scenario. d Increased to improve match with FBC phase screen. e In this case, 15 terms proved to be insufficient.
