MAKI: The Astro-E/Multi-Mission Observation VisualizerWelcome to the Observation Visualizer for Astro-E. This is powered by the LHEA plugin. Get it at the Plugin Page.
Obtaining the LHEA plugin
MAKI is a tool that accepts an image file from SkyView and plots it, along with when that target is visible during the current year. You may then place different satellite fields of view on top of the image, to plan out your observation. These FOVs may be rotated, and MAKI will indicate if the roll is allowed (green = good roll, yellow = bad roll, red = target simply not visible).
You can also view the sun angle visibility limits for several missions, as well as adding phase constraints and also seeing what the total overlapping window of opportunity for your selections is.
MAKI can handle almost any FITS image file. It also lets you save the results, and reload them. It does pop up its own window for all use.

That's it... MAKI will work from your tool and pop up a window for users to do work in.
A note on coordinate schemes. For all missions, the roll angle is defined in X-ray sky images ("look-up" direction); increasing roll angle corresponds to a counterclockwise rotation of the image. A few mission-specific details are noted here when appropriate.
A full API for the plotting and interactive functions in the LHEA plugin will be released later this year. Version 1.2 of MAKI has been released.
