I did see that but was new to creating a pixinsight script. Didn't realize the format of the array until I figured out the array or arrays. Successfully passed files to imagecalibration along witht the required parameters. Now to see if the execution works. I'm creating a script that will take a series of AAVSO files, match them up to the master gains, filters, and exposures and then calibrate them, reduce them in size, add missing FITS keywords, and create files that can be uploaded directly to Vphot. Haven't worked with scripts before and this was the last hurdle (invoking the sub processes from pixinsight). Thanks for the push in the right direction.
