Class SkyDensityMap
java.lang.Object
uk.ac.starlink.ttools.task.ConsumerTask
uk.ac.starlink.ttools.task.SingleMapperTask
uk.ac.starlink.ttools.task.SkyDensityMap
- All Implemented Interfaces:
- uk.ac.starlink.task.Task
public class SkyDensityMap
- extends SingleMapperTask
Calculates sky density maps and outputs them as tables.
The current implementation has the limitation that the same
combiner has to be used for all aggregated quantities.
If you want to calculate for instance the median of some quantities
and the mean of others, you're out of luck. It's hard to work out
what the parameters would look like to do it more generally.
