NAME
vmifuscience - Extract spectra from an IFU scientific exposure.
SYNOPSIS
esorex vmifuscience [OPTIONS] FILE.sof
DESCRIPTION
This recipe extracts IFU scientific spectra using the input extraction
mask, after aligning it to the brightest fiber spectra detected on the
input exposure. The extracted spectra are then resampled at a constant
wavelength step, after aligning the input wavelength calibration to the
positions of a set of identified sky lines. The extracted spectra are
eventually corrected for the relative differences in transmission from
fiber to fiber.

IFU_SCIENCE Raw Scientific spectra Y
MASTER_BIAS Calib Master bias Y
IFU_TRACE Calib Extraction mask Y
IFU_IDS Calib Wavelength calibration Y
IFU_TRANSMISSION Calib Transmission correction Y
EXTINCT_TABLE Calib Atmospheric extinction .
IFU_SPECPHOT_TABLE Calib Response curve .
CCD_TABLE Calib Bad pixel table .
Output files:
DO category: Data type: Explanation:
IFU_SCIENCE_REDUCED FITS image Reduced scientific spectra
IFU_SCIENCE_FLUX_REDUCED FITS image Reduced scientific spectra
IFU_FOV FITS image Reconstructed IFU field-of-view
IFU_SKY_TRACE FITS table Science aligned extraction mask
Only if sky alignment is requested:
IFU_SKY_IDS FITS table Sky aligned wavelength solution
The extraction mask, the wavelength calibration, and the relative
transmission table, are those generated by the recipe vmifucalib. A CCD
table must be specified only if a bad pixel cleaning is requested.
For more details, please refer to the VIMOS Pipeline Users Guide.
OPTIONS
--BiasMethod <str>
Bias removal method. (str; default: Zmaster). The full name of
this option for the EsoRex configuration file is
vimos.Parameters.bias.removing.method [default = Zmaster].
--CleanBadPixel <bool>
Bad pixel correction on master flat field. (bool; default:
False). The full name of this option for the EsoRex
configuration file is vimos.Parameters.badpixel.clean [default =
False].
--ApplyTransmission <bool>
Apply transmission correction to extracted scientific spectra
(bool; default: True). The full name of this option for the
EsoRex configuration file is vimos.Parameters.apply.transmission
[default = True].
--CalibrateFlux <bool>
Extracted spectra are flux calibrated. (bool; default: False).
The full name of this option for the EsoRex configuration file
is vimos.Parameters.flux.calibration [default = False].
--UseSkylines <bool>
Use sky lines to refine the wavelength calibration (bool;
default: True). The full name of this option for the EsoRex
configuration file is vimos.Parameters.sky.align [default =
True].
--UseSkyIndividual <bool>
Use sky lines to refine the wavelength calibration individually
for each spectrum (bool; default: False). The full name of this
option for the EsoRex configuration file is
vimos.Parameters.sky.individual [default = False].
--ComputeQC <bool>
Compute QC1 parameters (bool; default: False). The full name of
this option for the EsoRex configuration file is
vimos.Parameters.quality.enable [default = False].
Note that it is possible to create a configuration file containing
these options, along with suitable default values. Please refer to the
details provided by the 'esorex --help' command.

Access to source code provides access to a level of capabilities/information that companies protect though copyrights. Open source is a core component of the Internet and it is available to you. Leverage the billions of dollars in resources and capabilities to build a career, establish a business or change the world. The potential is endless for those who understand the opportunity.
Business Opportunity - Goldman Sachs, IBM and countless large corporations are leveraging open source to reduce costs, develop products and increase their bottom lines. Learn what these companies know about open source and how open source can give you the advantage.
Free Software
Free Software provides computer programs and capabilities at no cost but more importantly, it provides the freedom to run, edit, contribute to, and share the software. The importance of free software is a matter of access, not price. Software at no cost is a benefit but ownership rights to the software and source code is far more significant.
Free Office Software - The Libre Office suite provides top desktop productivity tools for free. This includes, a word processor, spreadsheet, presentation engine, drawing and flowcharting, database and math applications. Libre Office is available for Linux or Windows.
Free Books
The Free Books Library is a collection of thousands of the most popular public domain books in an online readable format. The collection includes great classical literature and more recent works where the U.S. copyright has expired. These books are yours to read and use without restrictions.
Source Code - Want to change a program or know how it works? Open Source provides the source code for its programs so that anyone can use, modify or learn how to write those programs themselves. Visit the GNU source code repositories to download the source.
Education
Study at Harvard, Stanford or MIT - Open edX provides free online courses from Harvard, MIT, Columbia, UC Berkeley and other top Universities. Hundreds of courses for almost all major subjects and course levels. Open edx also offers some paid courses and selected certifications.
Linux Manual Pages - A man or manual page is a form of software documentation found on Linux/Unix operating systems. Topics covered include computer programs (including library and system calls), formal standards and conventions, and even abstract concepts.
