v0.19.3

• Add object ID to FITS and annotation.

v0.19.2

• Add rate-sidereal track mode.

v0.19.1

• Add TRKMODE to fits header.

v0.19.0

• Add lambertian sphere brightness model for objects. Set object key model mode to lambertian_sphere and set albedo and size (meters) parameters. For 2D simulations, distance (km) and phase_angle (degrees) parameters must also be specified.

v0.18.0

• Add turbulent atmosphere to POPPY PSF generation. Set with psf option turbulent_atmosphere and sim option psf_sample_frequency.
• Add star and object segmentation annotation. Set sim option save_segmentation to true and star_annotation_threshold to limit stars annotated.

v0.17.1

• Copy useful TensorFlow Addon (TFA) functions into tfa as the TFA project is no longer maintained.
• Add tests.

v0.17.0

• Add JSON schema definitions. See schema/v1/Document.json for root schema file.
• Add observation object type.
• Add support for cropped sensors.
• Add altitude to site object. Set site alt parameter in km. Default is 0.

v0.16.0

• Add option to annotate stars. Set sim option star_annotation_threshold to the minimum star brightness magnitude or false to disable. Disabled by default.
• Add option to show annotated stars in annotated images. Set sim option show_star_boxes to true to enable.

v0.15.1

• Remove clipping of negative values in ground truth files by default.
• Fix missing dependencies for ground truth file generation.

v0.15.0

• Add support to save ground truth image data to the Annotations directory. Set sim option save_ground_truth to true.
• Add support for running on CPU with no GPU acceleration.
