• Locked Settings: While running, Flat Event order and most properties belonging to Flat Events are no longer editable until the run is terminated. Exceptions to this rule are that:
    • A Flat Event occurring later in the list than the currently running event, may be made Active / Inactive at any time.
    • The current Flat Event may be made Inactive and force movement onto the next Flat Event.
    • The number of Flat Event frames to capture can be increased or decreased at any time.
  • AutoFlats Recovery: AutoFlats is capable of recovering from a very limited set of issues that may be encountered during runtime. Specifically, AutoFlats can recognize, when capturing Sky Flats, if the act of simply “waiting” and letting a little time pass, may correct the issue. In other words, if you are capturing Dusk Flats and AutoFlats produces an error because it is unable to, at the minimum exposure length, produce a flat frame at or below the specified level, the run will simply pause and retry shortly (rather than fail and force you to so the same thing, but manually). The same is true for Dawn Flats (but opposite). Other errors seen during capture are currently not recoverable and will terminate the AutoFlats run.
  • Flat Frame File Naming: AutoFlats will use the same file naming pattern as the sequence to which it belongs. When using the “Target Name” as part of the file path, it should be noted that, due to the nature of Flat Frame data, the Target Name used in the file name may be a compound name.  For instance, if you have sequence targets m42 and m33 and each captures Light data at the same angle with the same filters, then flat frame data will be captured for both targets at the same time. In this case, the Target Name used for the flat frame would be “m42-m33”.
  • Flat Frame Deduplication: Many times, when Flat Events are added to the AutoFlats run, they are duplicative in nature. In other words, the Flat Events cover Light Events for multiple targets, but those Light Events are similar in that the same set of Flat Frames can function as calibration data for both. AutoFlats will automatically deduplicate these frames and will only capture a single set of data. It is important to note that the Flat Event list, when inspected visually, will not appear to deduplicate. The deduplication of flat frames is considered at runtime only. As a visual indicator that this is happening, you may see Flat Events other than the currently running event increment progress at the same time.
