Utility functions for observation simulation and image generation.

Functions

`draw_stars`(stars, *, t0, exptime, wcs0, ...)	Draw stars into an image while accounting for tracker motion during exposure.
`draw_sat`(orbit, *, t0, exptime, wcs0, ...[, ...])	Draw one or more tracked objects into an image.
`random_dark_time`(*, t_day, site, rng)	Draw a random time between the next sunset and next sunrise.
`random_boresight`(*, observer, t0, horizon, rng)	Draw a random boresight uniformly from the spherical cap above a horizon cut.
`random_disk`(center, radius, rng)	Draw an approximately uniform random point within a small spherical cap.
`generate_orbit`(height, coord, heading, ...)	Construct an orbit from line-of-sight geometry and assumed velocity components.
`get_line_gsobject`(p0, p1)	Construct a narrow line-shaped GalSim object between two sky positions.
`getLineGSObject`(p0, p1)	Construct a narrow line-shaped GalSim object between two sky positions.
`nostdout`()	Redirect stdout through a tqdm-compatible file wrapper.

File-like wrapper that routes writes through tqdm.write.
