X-ray Light Curve of GRO J1744-28 observed with RXTE/PCA on day 131 of 1996
J1744_d131_16s_lc image: X-ray light curve of GRO J1744-28 observed with RXTE/PCA. Bin width of each data is 16 seconds. X-ray light curve of GRO J1744-28 observed with RXTE/PCA. The source was observed from May 10 22:21 to 22:54, 1996. Bin #0 of X-axis corresponds to May 10 22:21:19, 1996 (UT). Bin width of each data is 16 seconds. Due to the problem with low temperature the observation was performed with 3 PCU's. This light curve includes background counts of roughly 960-1440 counts/bin.

X-ray Light Curve of GRO J1744-28 in finer time resolution
X-ray light curve of GRO J1744-28 observed with RXTE/PCA with 1-sec time resolution binning. The source was observed from May 10 22:21 to 22:54, 1996, and this light curve covers from 22:38:23 to 22:55:26. Due to the problem with low temperature the observation was performed with 3 PCU's. This light curve includes background counts of roughly 60-90 counts/bin. J1744_d131_1sec_lc image: X-ray light curve of GRO J1744-28 observed with RXTE/PCA with 1-sec time resolution binning.

Power Spectrum of GRO J1744-28 on day 131 (May 10, 1996)
J1744_d131_power image: Power spectrum of GRO J1744-28 observed with RXTE/PCA on day 131 (May 10, 1996). Power spectrum of GRO J1744-28 observed with RXTE/PCA on day 131 (May 10, 1996). This power spectrum is an ensemble average of 16 spectra, each of which are calculated from 128 seconds continuous data in 0.125 second bin. X-axis represents wave number (WN). Frequency of each WN is given as WN/128 (Hz). Peak at WN=274 (2.14Hz) corresponds to the coherent pulsation. Broad peak structure (QPO?) around WN=13 is also seen while the significance of the structure must be examined by detailed analysis.
