Are the Deep Field Q1 Tiles for the Deep Field Mosaics the maximum resolution images from the telescope?

Hi, 
   Is the resolution of the individual tiles that compose the 3 Deep Field Q1 mosaics the very maximum resolution captured by the telescope? (I'm referring to the individual tiles accessed via URLS in the script Download_Q1_Color_Tiles.sh cited in the notes for the Q1 Deep Fields in the ESASky web app.)

I had assumed they were, except I located the J041110.98-481939.3 gravitationally lensing cluster in tile EWS-Q1-EDFS-MosaicR4-290K230K_05_05.RGB.png from that script and compared it to the officially released 70x zoom image of the cluster available here (5000x2813 pixels) and it seems to me that the 70x zoom is a bit sharper than the tile. So is the telescope's captured full resolution image of the Deep Field South mosaic actually larger than 290K x 230K, and if so, what are the dimensions of the full resolution of that mosaic?
