This is for someone connected to the charts and sequences team: The chart/sequence updates page located here:

...shows a number of entries around star clusters with names like "NGC 2419 FOV". How does one access such a chart? It seems one cannot do it using that name or simply (in this case) "NGC 2419". If one uses the variable-star plotter to generate a chart using coordinates only, the chart gets made but shows no data. What's the trick?
