Description:We present an atlas of total slant-path columnar electron content data measured between the ATS-6 satellite and Ootacamund, India, a site near the magnetic Equator. Although these measurements were taken during a solar minimum, we summarize the general level of flare and geomagnetic activity that occurred during the observation period. These total content (NT) data were derived from the modulation phase (group delay) of a carrier signal transmitted from the geostationary satellite's Radio Beacon Experiment. Sudden changes in satellite pitch angle and possibly in roll, absolute calibration, and some sporadic noise contributed an error of about °4° to our results. This atlas contains two data sets: (1) NT as 2-min subsamples digitally recorded between 2 October 1975 and 28 January 1976, corrected for ATS-6 pitch maneuvers and (2) NT as 15-min subsamples chart recorded between 21 October 1975 and 22 July 1976 but uncorrected for changes in satellite orientation.
