This Readme file contains a description of the IRAS16293 Band 4
Science Verification data, scripts and data products. 

The dataset includes the CH3OH and CH3CN lines. One transition of CH3OH
-- 6(0,6) - 6(-1,6) (157.04862 GHz) -- is imaged as an example.

Additional information can be found at:
http://almascience.org/alma-data/science-verification

The Calibrated Data and Reference Images provided here were produced using
CASA version 4.5.0

IRAS16293_Band4_12m_Calibration.py is the calibration script.
IRAS16293_Band4_12m_Imaging.py is the imaging script.


IRAS16293_Band4_12m_UncalibratedData.tgz contains the raw data (one asdm dataset):

* uid___A002_X867766_Xa7


IRAS16293_Band4_12m_CalibratedData.tgz contains the calibrated uv-data:

* calibrated_final_cont.ms
* calibrated_final.ms.contsub

The file calibrated_final_cont.ms is the continuum uv dataset, and
calibrated_final.ms.contsub is the continuum subtracted CH3OH dataset.

To produce these calibrated datasets you will need to execute the calibration
script IRAS16293_Band4_12m_Calibration.py and follow the first few steps of
the script IRAS16293_Band4_12m_Imaging.py.


IRAS16293_Band4_12m_ReferenceImages.tgz contains the spectral line and continuum
image products:

* IRAS16293_Methanol_image.image.fits
* IRAS16293_Methanol_image.pbcor.fits
* IRAS16293_Methanol_image.flux.fits
* IRAS16293_Methanol_image.image.mom0.fits
* calibrated_final_cont_image.image.fits
