Alternative Data Release 1
There are holes in the sky coverage in the northern hemisphere.
This is from one observing session where all images were really bad. Investigation did not yield any solution. This area needs to be reobserved.
Some areas have a systematically low flux, sometimes even 40-50 percent.
This is because of bad data from a few observing sessions, affecting a few percent of the survey area. This requires further investigation.
3C 184.1 (07 43 01.4 +80 26 26) appears to have an additional lobe component on the south.
This is due to a local calibration error in one of two pointing images that were mosaicked together at this location. The wrong image will be updated.
