Comment 1 for bug 701509

I will take a look at how JHelioviewer currently handles scaling, but most likely I will need to use different approaches depending on the type of data. For instance, while EIT has a more accurate value for RSUN than CDELT, LASCO images do not have a value set for RSUN:

cat /var/www/jp2/v0.8/LASCO-C2/white-light/2010/09/04/2010_09_04__17_36_05_476__SOHO_LASCO_C2_white-light.jp2 | grep -a RSUN
<RSUN>0.0000000</RSUN>
