![Chandra observation of Algol seen with Profit, focussed on the 12-13A range.](../sshot/profit_algol_12A.png) |
As seen above, Profit can be used to "browse" a spectrum to simply scan regions of interest and make preliminary identifications. |
![Algol observation showing velocity profile around O VIII emission line.](../sshot/profit_algol_vel.png) |
Profit can also be used to measure the velocity profile of an
emission line, in this case the O VIII Ly Alpha line. The line is
slightly offset, suggesting either a doppler shift or a systematic data
error. |
![Profit with ACIS CCD data from the SNR W44.](../sshot/profit_w44_ccd.png) |
Profit will also work with CCD resolution data, in fact any
spectral data stored as a PHA file or even simply as a text file. In
addition, profit works in both wavelength units (as shown in the first two screenshots) and in energy units as shown above. |
![Profit with
Constellation-X simulated data around 6-7 keV](../sshot/profit_conx_xstar.png) |
Profit can use multiple atomic databases. Here the Fe K lines
from the XSTAR database are used to label the features seen in this
Con-X simulation. |
![Profit Chart shown
for Con-X data, breaking single spectral into 5 separate spectral plots.](../sshot/profit_conx_chart.png) |
Profit also has some "convenience" features. Here,
the Chart button has broken the Con-X spectrum shown in the previous
screenshot into 5 spectra, allowing individual features to be more
easily seen. |
