rubin_sim.moving_objects.run_obs(orbits, simdata, colmap, obs_file, footprint='camera', r_fov=1.75, x_tol=5, y_tol=3, eph_mode='nbody', prelim_eph_mode='nbody', obs_code='I11', eph_type='basic', t_step=1, rough_tol=10, obs_metadata=None)

Generate the observations.

Parameters:

orbitsrubin_sim.moving_objects.Orbit

Orbits for which to calculate observations

simdatanp.ndarray

The simulated pointing history data from OpSim

colmapdict

Dictionary of the column mappings (from column names here to opsim columns).

obs_filestr

Output file for the observations

footprintstr, opt

Footprint - camera, circle or rectangle. Default camera footprint.

r_fovfloat, opt

If using a circular FOV, this is the radius of that circle. Default 1.75, but only used if footprint is ‘circle’.

x_tolfloat, opt

If using a rectangular footprint, this is the tolerance in the RA direction. Default 5.

y_tolfloat, opt

If using a rectangular footprint, this is the tolerance in the Dec direction Default 3.

eph_modestr, opt

Ephemeris generation mode (2body or nbody) for exact matching. Default nbody.

prelim_eph_modestr, opt

Preliminary (rough grid) ephemeris generation mode (2body or nbody). Default nbody.

obs_codestr, opt

Observatory code for ephemeris generation. Default I11 = Cerro Pachon.

eph_typestr, opt

ephemeris type (from oorb.generate_ephemeris) to return (‘full’ or ‘basic’). Default ‘basic’.

t_stepfloat, opt

Time step for rough grid, in days. Default 1 day.

rough_tolfloat, opt

Tolerance in degrees between rough grid position and opsim pointings. Default 10 deg.

obs_metadatastr, opt

Metadata to write into output file header.
