This discreet bug was spotted by Mireille Huc a couple of weeks ago, but it had been bothering all SPOT4(Take5) data users for2 months : the L2A products were twice larger than necessary. The bug occurred when converting data to GeoTIFF format, it happened only on the production computer and not on the test computer. Unnecessary data were added to the files, which did not prevent us from reading the useful data normally.
The data have been corrected and loaded on the distribution server on October 10th. We advise you to download them again, they will take much less space on your disks.
