General Caveats
Please note that there are limitations inherent to the Operations Commissioning Phase (shared-risk environment). During early operations, we continue to learn more about the instruments and the environment that they are operating in, and some prior unknown technical limitations have been encountered. For ViSP for example, some of these limitations had an impact on the frame rate and as such the time spent on an individual slit position and the map cadences that ViSP can achieve.
In general, summit science operations staff (i.e., resident scientists and science operations specialists) strive to match the requests of any observing proposal the best they can, but there are no guarantees that for example, the lengths of observations, cadences or the requested seeing will be 100% consistent with the proposal. If you do have any questions about (summit) science operations and the execution of your observing program(s) you may also contact the DKIST Program Scientist for Operations atritschler@nso.edu or use the DKIST Help Desk.
It is not recommended to use Cycle 1 data for science analysis. Although there are some good datasets available from Cycle 1, substantial improvements to the data taken and the calibration routines have subsequently been made. For ease of scientific use, we recommend Users perform their analyses with data from Cycle 2 onwards.
