Welcome !
This program uses around 700 hours per year on two of the telescopes operated by the Small and Moderate Aperture Research Telescope System (SMARTS) at Cerro Tololo Interamerican Observatory (CTIO) in Chile to observe all public Large Area Telescope (LAT) monitored blazars that are accessible from Chile. The data generated is used to study the relationship between the emission peak in optical/IR bandpasses and the public Fermi gamma-ray emission. Data and results from the SMARTS telescopes are made public on this weg page on a timescale comparable to that of the LAT data.

Recalibration of Selected Comparison Stars
The optical magnitudes of the comparison stars for the following fields were previously quoted from the USNOB1 and UCAC4 catalogs. However, recently we calculated the magnitudes of the comparison stars against photometric standards from the Landolt catalog. The targets which should have changed are listed below:
0235-618, 0301-243, 0250-225, 0402-362, 0426-380, 0454-234, 0454-46, 0458-02, 0637-75, 0531-4827, 0537-441, 0850-1213, 1004-217, 1144-379, 1244-255, 1514-241, 1622-297, 1717-5156, 1424-41, 2052-474, 2142-75, 2233-148, 2326-502, 2345-1555, 2345-16, 3C446, 3C454.3
Ideally, we will do this procedure for all targets. However, we require many observations of these targets on photometric nights to do this calculation. As a result, it will be a bit longer for our newer targets and targets that are viewed with lower observing cadence. Please email us at glast@yale.edu with any questions.
