Aims. We seek to provide 2MASS and OGLE identifications and coordinates for all stars in the finding chart published by Arp (1965, ApJ, 141, 43). This chart covers the low extinction area around NGC 6522, also known as Baade’s window, at coordinates (l,b) = (1.02, −3.92).
Methods. A cross correlation, using numerical techniques, was performed between a scan of the original finding chart from Arp and 2MASS and OGLE-II images and stellar coordinates.
Results. We provide coordinates for all stars in Arp’s finding chart and 2MASS and OGLE identifications wherever possible. Two identifications in quadrant II do not appear in the original finding chart.
