It seems the BasicCCDParameters script was updated somewhat recently, adding the ability to choose an ROI. I have found a few bugs with it. First, it seems that in one line of code, `this.` was being used to reference variables, such as x0/y0 and width/height, that did not need a context. This resulted in the following error message in the console:
Processing script file: C:/Program Files/PixInsight/src/scripts/CCDParameters.js
CCD Parameters Script started
** Warning [162]: C:/Program Files/PixInsight/src/scripts/CCDParameters.js, line 153: reference to undefined property this.x0
I edited the script and removed `this.` from each variable of that line, and it corrected the error.
