Change Log¶

This document records the main changes to the BMO code.

0.2.0 (2017-10-09)¶

BMO now provides a full logging system which also catches Twisted messages.
A fake Vimba controller which provides at least some basic functionality like connecting a camera.
Outputs actorkeys keywords for camera devices, exposure state, and controller.
Finding charts are now, by default, grabbed from platelist.
Acquisition camera positions on the plates are grabbed from the DB.
Partially filled up documentation on how to use BMO.
Last centroid positions are stored and used if centre_up fails getting centroid position from the DS9 regions.
Logging now allows to redirect debug, info, and warning messages to the actor. This prevents you from having to do a log.debug and a actor.writeToUsers for the same message. Instead, just do log.debug('message', actor=actor).

Exposing the cameras is now asynchronous. Both cameras can be exposed at the same time without blocking.
Background estimation now only happens for the first image in the series. For any subsequent image, the first background is subtracted. If the exposure time changes, the background is recalculated.
bmo ds9 clear is now an alias to bmo ds9 reset.

Thanks to the asynchronous exposing, the problem with TCC status timing out during centring up should now be fixed.
Better handling of TCC disconnections and reconnections.

This is the first release of BMO so this list includes only the most notable features to date.

Base actor based on twistedActor and TCC device.
Basic camera control for Allied Vision Manta devices, with camera auto-discovery.
Display of camera images using DS9 and XPA.
Command parser based on click. Help commands are broadcasted as responses to the user.
Basic set of camera control commands (expose, exptime, reconnect).
Loaded cart auto-detection and finding chart display.
Centroid detection based on PyGuide.
Centre-up in translation (RA/Dec) and rotation.
Image background subtraction using photutils.
Basic astrometry for images.
Sphinx documentation. Uses sphinx-click to auto-generate available commands.
