Applying the GTI

Now that we have GTI file, we can apply it to the event file by running rgsproc again. rgsproc is a complex task, running several steps, with five different entry and exit points. It is not necessary to rerun all the steps in the procudure, only the ones involving filtering.

To rerun the pipeline in the GUI:

1)

Call rgsproc in the Available Tools panel.

2)

Next to ``reflection orders for spectrum generation'', make sure it is set for both orders, 1 2 .

3)

Next to ``(re)start processing at'' and ``conclude processing at'', use the pull-down menus to select 3:filter and 5:fluxing, respectively.

4)

Next to ``Additional GTI tables'', enter the name of the GTI file, r1_gti.fits.

5)

Verify that ``background correct the spectra'' is set to no.

6)

Verify that ``Produce column with m*lambda (source at requested position) is set to ``yes''.

7)

Click on ``Run''.

We will refer to the output file as r1_filt.fits.

To rerun the pipeline from the Command Window:

rgsproc orders='1 2' auxgtitables=r1_gti.fits bkgcorrect=no
$$ withmlambdacolumn=yes entrystage=3:filter finalstage=5:fluxing

where

orders - spectral orders to be processed
auxgtitables - gti file in FITS format
bkgcorrect - subtract background from source spectra?
withmlambdacolumn - include a wavelength column in the event file product
entrystage - stage at which to begin processing
finalstage - stage at which to end processing

We will refer to the output file as r1_filt.fits.
