HLTau_Band7_UncalibratedData.tgz contains the raw data:

Ten asdm datasets:
* uid___A002_X91cc20_X20a
* uid___A002_X91cc20_X6d8
* uid___A002_X91cc20_Xa16

* uid___A002_X925649_X5ab
* uid___A002_X928687_X446
* uid___A002_X928687_Xab


HLTau_Band7_CalibratedData.tgz contains the calibrated uv-data:

* HLTau_B7cont.calavg
* calibration

To produce this calibrated dataset you will need to execute the calibration
scripts in HLTau_Band7_CalibrationScripts.tgz and follow the imaging script
that is located at the CASA guide page listed above.

The directory "calibration" contains the self-calibration tables that are
produced as part of the imaging script. Users can use these tables to
self-calibrate the provided calibrated data. Alternatively, users can perform
self-calibration and generate these tables by following the provided imaging
scripts that are located on the CASA guide page. Note that self-calibration
was not performed on the line data.


HLTau_Band7_ReferenceImages.tgz contains the image product:

* HLTau_B7cont_mscale_ap.image.pbcor.fits

The synthesized beam size for this image is 30 x 19 mas.


HLTau_Band6+7_ReferenceImages.tgz contains the 1.0 mm combined Band6 and Band 7 continuum image products:

* HLTau_B6B7cont_mscale_n2_ap.image.alpha.error.fits
* HLTau_B6B7cont_mscale_n2_ap.image.alpha.fits
* HLTau_B6B7cont_mscale_n2_ap.image.tt0.fits
