CDF档案:Herschel PACS和SPIRE光谱数据管道和原恒星和年轻恒星对象的产品
The CDF Archive: Herschel PACS and SPIRE Spectroscopic Data Pipeline and Products for Protostars and Young Stellar Objects
摘要:
我们展示了COPS-DIGIT-FOOSH(CDF)赫歇尔光谱数据产品档案和相关的辅助数据产品,以及数据保真度评估,以及与Herschel-PACS和SPIRE ICC小组合作创建的用户档案。我们的产品包括数据立方体,等高线图,自动线拟合结果,和最好的一维光谱产品的所有原恒星和磁盘源观察与PACS在RangeScan模式的两个观测程序:DIGIT开放时间关键程序(KPOT_nevans_1和SDP_nevans_1; PI:N。Evans)和FOOSH开放时间程序(OT1_jgreen02_2; PI:J. Green)。此外,我们还为COPS开放时间计划(OT2_jgreen02_6; PI:J. Green)和FOOSH源提供最好的SPIRE-FTS光谱产品。我们包括数据处理的细节,输出产品的描述,以及用户应用程序的可靠性测试。我们确定了要谨慎使用的数据集部分。由此产生的绝对通量校准几乎在所有情况下都得到了改善。与以前的减少相比,由此产生的旋转温度和CO分子的数量在一些来源中发生了很大的变化。然而,平均而言,旋转温度基本上没有变化(< 2%),但温暖的(Trot ~ 300 K)CO分子的数量增加了约18%。
英文摘要:
We present the COPS-DIGIT-FOOSH (CDF) Herschel spectroscopy data product archive, and related ancillary data products, along with data fidelity assessments, and a user-created archive in collaboration with the Herschel-PACS and SPIRE ICC groups. Our products include datacubes, contour maps, automated line fitting results, and best 1-D spectra products for all protostellar and disk sources observed with PACS in RangeScan mode for two observing programs: the DIGIT Open Time Key Program (KPOT_nevans_1 and SDP_nevans_1; PI: N. Evans), and the FOOSH Open Time Program (OT1_jgreen02_2; PI: J. Green). In addition, we provide our best SPIRE-FTS spectroscopic products for the COPS Open Time Program (OT2_jgreen02_6; PI: J. Green) and FOOSH sources. We include details of data processing, descriptions of output products, and tests of their reliability for user applications. We identify the parts of the dataset to be used with caution. The resulting absolute flux calibration has improved in almost all cases. Compared to previous reductions, the resulting rotational temperatures and numbers of CO molecules have changed substantially in some sources. On average, however, the rotational temperatures have not changed substantially (< 2%), but the number of warm (Trot ~ 300 K) CO molecules has increased by about 18%.
