For Developers


Developer Documentation

Documentation, examples and code for working with LCO's extensive programmatic interfaces.

Finer Points

Special Scheduling Modes

Rapid Response mode is for observations of science targets (e.g. gamma-ray bursts) that must be carried-out as soon as possible after a request is submitted. Time-Critical mode is for observations at tightly constrained times that rarely occur.

Photometric Standard Stars

Observations of standard stars are routinely acquired to enable the photometric calibration of science data, as well as to monitor the performance of the network’s telescopes. The data from these observations are available to all in the Science Archive.

Time Refund Policy

If data are unusable because of a technical problem arising from LCO's hardware or software, the time charged for that observation may be refunded to the proposal.

Airmass Limit

Advice on setting your airmass limit for best quality data

User Quotas

The time available to Co-investigators on a proposal (for observation requests) may be restricted by the proposal's PI. Read how user quotas work and how to enable them.

Orbital Elements for Close-approaching NEOs

The orbital elements of close-approaching NEOs evolve rapidly, but the time and site of an observation is not known until a request is scheduled. This document provides some guidance.

Astrometric Solutions Thwarted by Saturated Pixels

Some images, acquired under good conditions, resist astrometric solutions. We’ve determined that pixel saturation is critical for determining whether an astrometric (WCS) solution is fit to an image.

Ghosts in SBIG 6303 camera images

Bright stars can leave "ghosts" in the SBIG 6303 camera images (on the 0.4m telescopes). Find out why they occur, and how to spot them.

Information on Submitted Observing Requests

A description of the information on submitted observing requests now available in the observatory portal.

Intra/Inter Proposal Priority (IPP) Factor

The system for prioritizing observing requests.

Photometric nonlinearity in SBIG 6303 camera images

Some SBIG 6303 cameras show a nonlinear response when the sky background is low. Photometry affected by this problem can be improved by applying empirically-derived corrections.
