A search for another exoplanet in the same system can also be performed using the OOT data that might contain small depth features that repeat with a different period than the main transits.

The AXA was opened for anyone to submit observations that were likely to be added to the AXA web pages and maintained as a historical archive.In this way amateurs with good observing skills can contribute to the professional astronomy community's growing understanding of exoplanet systems, and possibly produce interest in anomalies that could lead to the discovery of additional exoplanets in the same exo-planetary system.This web page describes how anyone who has observed an exoplanet, and produced a light curve (LC), can submit their observations and have them added to the archive.Pulitzer Prize-winning photographer Brian Smith creates iconic portraits of the famous and infamous for magazines, books and advertising.He has appeared on The X Factor, Fine Living Network and Israel Channel One and exhibited at the Library of Congress and the Aperture Gallery.Original Purpose for this Archive Observation Submission Format Sampe of Archive Processed Product Explosive Growth of Exoplanet Discoveries Patterns to Look For Observing Philosophy Aperture vs.

A notation may be made on the LC plot showing 2-minute RMS of the individual measurements.

When many transits are present on a web page devoted to an exoplanet, and ordered with the most recent LC at the top, it is easy to notice the following patterns: transists occuring early or late (implying a need for refining the orbital period), depths varying in a systematic way with filter (related to star spectral type and center miss distance) and transit length varying over time.

Since amateurs have larger systematic errors I have included the lower panel to show the same data before removal of these systematic errors.

The lower panel also shows a air mass and "loss" plots (described below).

As the archive manager I will assess the quality of the data and if it looks acceptable (99% of submissions are acceptable) I will proceed to process it.
