APT Target Confirmation Charts

Target coordinates and JWST pointing can be verified by viewing the coordinate position superimposed onto digital sky data.

Target Confirmation charts are a functionality within APT that provides users with a convenient way to verify that their target coordinates are going to position the telescope in the expected place. This functionality works exactly the same between the HST and JWST branches of APT. For each fixed target, a target confirmation chart is exported as a PDF file by APT. An option is also presented to open the exported charts in an external PDF viewer, as seen in Figure 1. If you have entered proper motion information into the APT Targets GUI for a target, this gets applied to the position shown on the PDF chart. Figure 2 shows an example.
