Lossless compression of simulated radio interferometric visibilities

Open Access

Table 3

Sisco compression results on observed (and therefore noisy) data.

Test set	No predict (%)	Linear (%)	Flags (%)
MWA	59.1	64.9	40
MeerKAT	53.1	57.7	62
LOFAR HBA	79.4	86.7	40
LOFAR LBA	84.1	92.3	0

Gaussian data	84.1	92.3	0

Notes. The listed values are the resulting fractional size after compression in percentages. DEFLATE level 9 was used. The last column lists the percentage of flagged visibilities, which has a substantial effect on compression.
