lvmsurveysim 0.8.3

Pickup a few minor bugfixes since last release. Also include new extended survey.

lvmsurveysim 0.8.2

• Fix a very silly bug that could lead to incorrect statistics being printed/plotted.

lvmsurveysim 0.8.1

This is mainly a bugfix release:

• Fix bug in tiling that manifests itself as slightly misaligned tiles at high declinations

• Tile strictly along great circles

• Allow overlap between neighboring tiles, default to ~4.1% which is 1 row of fibers

lvmsurveysim 0.8.0

• Reworked tiling to support tile unions: groups of (overlapping) targets tiled together to form a uniform grid
• Tiling now considers tile density in addition to target priority when tiling overlapping targets
• Support removing overlapping tiles from full-sky sparse grid
• Reworked representation of sky regions to be based on proper spherical polygons
• No longer uses Shapely regions
• Many small improvements and bugfixes

lvmsurveysim 0.5.1

First release supporting operations database in SQL.

• all database functions are encapsulated in lvmsurveysim.schedule.opsdb.py
• uses peewee, but nothing specific about it escapes opsdb.py
• still supports FITS tables as persistence format for easier development work
• see run_schedule.py for example usage
• fix issues in sphinx documentation

lvmsurveysim 0.3.1

• Fixed bugs related to recent changes in plotting
• Added unique tileid to tile database and schedule output table
• Added Tile class carrying all tile data, in preparation for standard stars, guide stars

lvmsurveysim 0.3.0

The survey tiling step has been separated out into a (persistent) tile database object. The survey scheduling stage now expects nothing more than a tile database to operate.

lvmsurveysim 0.2.5

• Add scheduling via shadow height
• Add all-sky target
• Add sparsly sampled targets
• Speed up overlap calculation
• Save and restore overlap in npy file
• Improve survey analysis tools and plots

lvmsurveysim 0.2.0

• Better save and restore of Scheduler objects.
• Improved plotting of the results of the scheduler.
• Implemented tiling of regions using an hexagonal, monolithic IFU. This tiling mode is now the default one.
• New Scheduler.print_statistics, Scheduler.get_target_time, and Scheduler.plot_survey methods.
• Implemented zenith avoidance, multiple exposures per pointing, minimum exposures per visit, and other improvements in the Scheduler class.
• Many other changes.

lvmsurveysim 0.1.0

• Initial release.
