CO Visibilities, Image Cubes, Moment Maps and Radial profiles (ARKS IV)

This dataset includes the CO data from the ARKS large program. For the gas-bearing systems, we include zipped files of the 12CO visibilities, the 13CO visibilites, the image cubes and the moment maps, produced with the robust parameter set to 0.5 and to 2. We also include the radial profiles for the gas bearing systems presented in the ARKS IV paper: for HD9672, HD121617 and HD131835, these are azimuthally averaged radial profiles created from the robust = 0.5 image cubes. For HD32297 and HD131488, these are non-deprojected, on-sky radial profiles created by vertically averaging the emission perpendicular to the disc mid-plane in the robust = 2 moment 0 maps. For the gas-free systems, we include the 12CO visilbilites, the 13CO visbiliities and the image cubes, produced with the robust parameter set to 2 to maximise the signal to noise ratio. In each image cube folder, we include the .image, .psf, .pb, .residual created by the CLEANing process. We also include the Keplerian mask (.mask file) used to CLEAN the data.

本数据集包含ARKS大项目产生的一氧化碳（CO）相关数据。针对含气系统，我们提供了12CO视见度数据、13CO视见度数据、图像立方体（image cubes）以及矩图（moment maps）的压缩文件，上述数据均通过将鲁棒参数（robust parameter）分别设置为0.5与2的流程生成。此外，我们还提供了ARKS IV论文中提及的含气系统的径向轮廓数据：针对HD9672、HD121617与HD131835，此类径向轮廓为从鲁棒参数=0.5的图像立方体中提取的方位平均径向轮廓；针对HD32297与HD131488，此类径向轮廓为未去投影的天球径向轮廓，通过在鲁棒参数=2的零阶矩图（moment 0 maps）中沿垂直于盘的中平面的方向对发射信号进行积分平均得到。针对不含气系统，我们提供了通过将鲁棒参数设置为2以最大化信噪比的流程生成的12CO视见度数据、13CO视见度数据以及图像立方体。在每个图像立方体文件夹内，均包含由Clean（CLEAN）成像流程生成的.image、.psf、.pb与.residual文件。我们还提供了用于数据Clean处理的开普勒掩模（Keplerian mask，.mask文件）。
