The authors' main claim We report the discovery with BeppoSAX of a new 170.84 +/- 0.04 s X-ray pulsar, 1SAX J1324.4-6200, found serendipitously in the field of the X-ray binary X1323-619 in 1997 August.

The compiled record

The paper's own sentences, arranged. Each label is drawn from a closed vocabulary; the number beside it is the probability the classifier gave that label. Numbers in the tables are the authors', checked by code. No sentence in this record was written by a model.

The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

We report the discovery with BeppoSAX of a new 170.84 +/- 0.04 s X-ray pulsar, 1SAX J1324.4-6200, found serendipitously in the field of the X-ray binary X1323-619 in 1997 August. The source and periodicity are also detected in archival ASCA data taken in 1994. The X-ray spectrum is modeled by a power-law with a photon index of 1.0 +/- 0.4 and absorption of (7.8 +2.7 -1.1) 10^22 atom cm-2. The source is located close to the galactic plane and within 3 arcmin of the direction of the dark cloud DC 306.8+0.6. The measured interstellar absorption and cloud size imply a distance >3.4 kpc. This implies a 1-10 keV source luminosity of >1.1 10^34 erg/sec during the BeppoSAX observation. The source is not detected in earlier Einstein IPC and EXOSAT CMA observations, most probably due to reduced detector efficency and lower sensitivity to highly absorbed sources. The X-ray properties suggest that 1SAX J1324.4-6200 is an accreting neutron star with a Be star companion.

The source and periodicity are also detected in archival ASCA data taken in 1994. The X-ray spectrum is modeled by a power-law with a photon index of 1.0 +/- 0.4 and absorption of (7.8 +2.7 -1.1) 10^22 atom cm-2. The source is located close to the galactic plane and within 3 arcmin of the direction of the dark cloud DC 306.8+0.6. The measured interstellar absorption and cloud size imply a distance >3.4 kpc. This implies a 1-10 keV source luminosity of >1.1 10^34 erg/sec during the BeppoSAX observation. The source is not detected in earlier Einstein IPC and EXOSAT CMA observations, most probably due to reduced detector efficency and lower sensitivity to highly absorbed sources.
