Integrated intensities for CH3OH and H2CO toward 8 GMCs in NGC 253 (Tables 1 and 2 in Huang+2025)

These datasets include the full versions of Tables 1 and 2 from Huang et. al (2025), "Investigating the chemical link between H2CO and CH3OH within the CMZ of NGC 253". Within the datasets are the integrated intensities and associated uncertainties of measurements of various transitions of methanol (CH3OH) and formaldehyde (H2CO) toward 8 Giant Molecular Clouds in NGC 253. Note that some transitions of each molecule are blended with other transitions of the same molecule, forming blending groups such that only one intensity measurement is extracted per blending group. In these tables, transition information for each of the components of the blending group are combined into one row, with the relevant information for each transition within the group provided but with a sinlge integrated intensity and uncertainty measurement listed per blending group. The descriptions and units of the columns in each table are as follows: spin: the spin isomer(s) of the transition (E or A for CH3OH, o or p for H2CO), string transitions: the transition(s) of interest, string frequency: the frequency in gigahertz [GHz] of the transition(s), float E_u: the upper-state energy in Kelvin [K] for the transition(s) of interest, float A_ul: the Einstein A coefficient for the transition(s) of interest in units of inverse seconds [1/s], float GMC1a: integrated intensity of the transition(s) of interest toward GMC 1a in units of Kelvin kilometers per second [K km/s], float sig1a: the uncertainty associated with the integrated intensity measurement toward GMC 1a in units of Kelvin kilometers per second [K km/s], float GMC2b: integrated intensity of the transition(s) of interest toward GMC 2b in units of Kelvin kilometers per second [K km/s], float sig2b: the uncertainty associated with the integrated intensity measurement toward GMC 2b in units of Kelvin kilometers per second [K km/s], float GMC3: integrated intensity of the transition(s) of interest toward GMC 3 in units of Kelvin kilometers per second [K km/s], float sig3: the uncertainty associated with the integrated intensity measurement toward GMC 3 in units of Kelvin kilometers per second [K km/s], float GMC4: integrated intensity of the transition(s) of interest toward GMC 4 in units of Kelvin kilometers per second [K km/s], float sig4: the uncertainty associated with the integrated intensity measurement toward GMC 4 in units of Kelvin kilometers per second [K km/s], float GMC6: integrated intensity of the transition(s) of interest toward GMC 6 in units of Kelvin kilometers per second [K km/s], float sig6: the uncertainty associated with the integrated intensity measurement toward GMC 6 in units of Kelvin kilometers per second [K km/s], float GMC7: integrated intensity of the transition(s) of interest toward GMC 7 in units of Kelvin kilometers per second [K km/s], float sig7: the uncertainty associated with the integrated intensity measurement toward GMC 7 in units of Kelvin kilometers per second [K km/s], float GMC8a: integrated intensity of the transition(s) of interest toward GMC 8a in units of Kelvin kilometers per second [K km/s], float sig8a: the uncertainty associated with the integrated intensity measurement toward GMC 8a in units of Kelvin kilometers per second [K km/s], float GMC9a: integrated intensity of the transition(s) of interest toward GMC 9a in units of Kelvin kilometers per second [K km/s], float sig9a: the uncertainty associated with the integrated intensity measurement toward GMC 9a in units of Kelvin kilometers per second [K km/s], float本数据集包含Huang等人（2025）发表的论文《探究NGC 253中央分子区（Central Molecular Zone, CMZ）内甲醛（H2CO）与甲醇（CH3OH）的化学关联》中的表1与表2完整版本。数据集包含针对NGC 253中8个巨分子云（Giant Molecular Cloud, GMC）测得的甲醇（CH3OH）与甲醛（H2CO）各跃迁的积分强度及对应不确定度。需注意，部分分子的跃迁会与该分子自身的其他跃迁发生谱线混叠，形成混叠组，每个混叠组仅能提取出一组强度测量值。此类表格中，混叠组各组分的跃迁信息会被整合至同一行，同时列出组内各跃迁的相关信息，但每个混叠组仅对应一组积分强度与不确定度测量结果。各表格的列含义与单位说明如下： spin：跃迁的自旋异构体（甲醇（CH3OH）对应E型或A型，甲醛（H2CO）对应正（ortho, o）型或仲（para, p）型），数据类型为字符串； transitions：目标跃迁，数据类型为字符串； frequency：目标跃迁的频率，单位为吉赫（GHz），数据类型为浮点型； E_u：目标跃迁的上态能量，单位为开尔文（K），数据类型为浮点型； A_ul：目标跃迁的爱因斯坦A系数，单位为每秒（1/s），数据类型为浮点型； GMC1a：指向GMC 1a测得的目标跃迁积分强度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； sig1a：指向GMC 1a的积分强度测量值对应的不确定度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； GMC2b：指向GMC 2b测得的目标跃迁积分强度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； sig2b：指向GMC 2b的积分强度测量值对应的不确定度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； GMC3：指向GMC 3测得的目标跃迁积分强度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； sig3：指向GMC 3的积分强度测量值对应的不确定度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； GMC4：指向GMC 4测得的目标跃迁积分强度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； sig4：指向GMC 4的积分强度测量值对应的不确定度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； GMC6：指向GMC 6测得的目标跃迁积分强度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； sig6：指向GMC 6的积分强度测量值对应的不确定度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； GMC7：指向GMC 7测得的目标跃迁积分强度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； sig7：指向GMC 7的积分强度测量值对应的不确定度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； GMC8a：指向GMC 8a测得的目标跃迁积分强度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； sig8a：指向GMC 8a的积分强度测量值对应的不确定度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； GMC9a：指向GMC 9a测得的目标跃迁积分强度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型； sig9a：指向GMC 9a的积分强度测量值对应的不确定度，单位为开尔文·千米每秒（K·km/s），数据类型为浮点型。
