The files RXJ_[U,B,V,R,I]_new.fits are exactly aligned and objects
coincide on a pixel by pixel basis. Pixel scale is 0.1 arcsec). The
K-band (RXJ_K_paste.fits) has a different pixel scale (0.148 arcsec)
and represents a subarea of the optical data.
Please note that there are no weight maps for the U and K bands.

Vega magnitude zeropoints for the RXJ1347 VLT data are:

U: 24.07
B: 26.896
V: 27.39
R: 27.36
I: 26.641
K: 24.14
