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.

本数据集收录了ARKS大项目的一氧化碳（CO）相关观测数据。针对含气系统，我们提供了12CO可见度数据、13CO可见度数据、图像立方体（image cubes）以及矩图（moment maps）的压缩包，所有数据均采用设置为0.5和2的鲁棒参数（robust parameter）生成。此外，我们还提供了ARKS IV论文中提及的含气系统径向轮廓：对于HD9672、HD121617与HD131835，该类轮廓为从鲁棒参数=0.5的图像立方体中提取的方位平均径向轮廓；对于HD32297和HD131488，该类轮廓则是通过在鲁棒参数=2的矩0图中沿垂直于盘面中平面的方向对发射强度进行垂直平均得到的未去投影天面径向轮廓。针对不含气系统，我们提供了采用鲁棒参数设为2以最大化信噪比的12CO可见度数据、13CO可见度数据以及图像立方体。在每个图像立方体文件夹中，均包含由CLEAN流程生成的.image、.psf、.pb与.residual文件。我们还同步提供了用于数据CLEAN处理的开普勒掩模（Keplerian mask，.mask文件）。
