X-ray Light Curve of GRO J1744-28 observed with RXTE/PCA on day 131 of 1996
|
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.

Power Spectrum of GRO J1744-28 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.
