A method for collecting data regarding the operating condition of a nuclear reactor core including: positioning a first linear array of gamma thermometer (GT) sensors in a first instrument housing, wherein the GT sensors are arranged asymmetrically along the first linear array; positioning a second linear array of GT sensors in a second instrument housing, wherein the GT sensors are arranged asymmetrically along the second linear array and wherein the second linear array of GT sensors is asymmetrical with respect to the first linear array of GT sensors; positioning the first instrument housing in the reactor core at a first core location and positioning the second instrument housing at a second core location symmetrical with respect to the first core location; collecting core condition data from at least one of the GT sensors in the first linear array of GT sensors, and applying the collected core condition data as data collected from the second linear array. Detector calibration can be accomplished by using the adjacent GT sensor, the closest GT sensor in the string (if the adjacent GT sensor is unavailable) or by using the GT sensor in a symmetric string that has a close axial height to the adjacent GT sensor.
