Change in S-ALCDEF 2.2:
Single observations in a lightcurve block are no longer allowed.
Each lightcurve block must have at least 2, preferably 5 or more, observations.
If not named and/or numbered, objects must have an MPC designation. Do not submit data for NEOCP
objects or those using a custom designation.
View the ALCDEF standards documentation,
which describes the data and formatting for the values associated with the keywords in the two data sections.
An appendix details the requirements for submitting "simple" data.
The fields in the Required Data section will apply to all submitted dataexcept for the ALLOWSHARING and SUBMITPDS settings. These can be altered with metadata overrides. All other settings are fixed.
The fields in the Base Data section will be applied to all light curve blocks unless their
corresponding keywords appear within a given light curve block. This allows, e.g., submitting data for multiple
asteroids or filters within the same file.
