The search was performed in the summed power spectra. With an accumulation time equivalent to 100 hours of continuous observations for each point of the area, 5 known pulsars were found with a signal-to-noise ratio (S/N) from 20 to 1300 in the first harmonic of the spectrum. Average profiles are obtained for the detected pulsars. Estimates are given for the peak and integrated flux densities of the found pulsars for individual sessions and for power spectra summed over 5.5 years, using the developed method based on measurements of harmonic heights in the power spectrum. No new pulsars were found in the area. Apparently, when searching for pulsars in the area, we approached the lower limit of the luminosity of second pulsars. The survey completeness is at the level of 0.5 mJy.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324812688">На антенне БСА ФИАН проведен поиск пульсаров вне плоскости Галактики в площадке размером 300 кв. град. на частоте 111 МГц, с чувствительностью в 5–10 раз лучше, чем у ранее проводимых обзоров. Поиск проводился в суммированных спектрах мощности. При накоплении, эквивалентном 100 ч непрерывных наблюдений для каждой точки площадки, обнаружено 5 известных пульсаров, имеющих отношение сигнала к шуму (СШ) от 20 до 1300 в первой гармонике спектра. Для обнаруженных пульсаров получены средние профили. Даны оценки пиковой и интегральной плотностей потока найденных пульсаров для отдельных сеансов и для суммированных за 5.5 лет спектров мощности, полученные с использованием разработанного способа, основанного на измерениях высоты гармоник в спектре мощности. Новые пульсары в площадке не обнаружены. По-видимому, при поиске пульсаров в площадке мы приблизились к нижней границе светимости секундных пульсаров. Полнота обзора находится на уровне 0.5 мЯн.</p></trans-abstract><kwd-group xml:lang="en"><kwd>pulsar</kwd><kwd>power spectrum</kwd><kwd>average profile</kwd><kwd>flux density</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>пульсар</kwd><kwd>спектр мощности</kwd><kwd>средний профиль</kwd><kwd>плотность потока</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>R.
