Data Sets

The following data sets are available for use with candl. For the default data sets that ship with the release there are shortcuts available to access them easily (see below). You can also use candl.data.print_all_shortcuts() to list all available shortcuts. New data sets will be uploaded as they become available.

Default Data Sets

The pip installation of candl ships with the data sets below. These are by default in your python site-packages/ folder along with the code. You may choose to move them to a more convenient location (this will break the default short cuts, though you can override them).

SPT-3G 2018 TT/TE/EE

Paper(s):

L. Balkenhol, D. Dutcher, A. Spurio Mancini, A. Dussot, K. Benabed, S. Galli et al. (SPT-3G Collaboration)

Type:

Primary power spectrum measurement (\(TT/TE/EE\))

Website:

SPT-3G Website

LAMBDA:

NASA Archive

Short cut(s):

candl.data.SPT3G_2018_TTTEEE

Latest version:

v0

SPT-3G 2018 PP

Paper(s):

Z. Pan, F. Bianchini, W. L. K. Wu et al. (SPT-3G Collaboration)

Type:

Lensing power spectrum measurement (\(\phi\phi\))

Short cut(s):

candl.data.SPT3G_2018_Lens, candl.data.SPT3G_2018_Lens_and_CMB

Latest version:

v0

Note: this data set uses the lensing power spectrum in \(\phi\phi\). Use candl.data.SPT3G_2018_Lens when only working with lensing data, use candl.data.SPT3G_2018_Lens_and_CMB when combining lensing and primary CMB data.

ACT DR4 TT/TE/EE

Paper(s):

S. Aiola, E. Calabrese, L. Maurin, S. Naess, B. L. Schmitt et al. (ACT Collaboration)

S. K. Choi, M. Hasselfield, S.-P. P. Ho, B. Koopman, M. Lungu et al. (ACT Collaboration)

Type:

Primary power spectrum measurement (\(TT/TE/EE\))

LAMBDA:

NASA archive

Short cut(s):

candl.data.ACT_DR4_TTTEEE

Latest version:

v0

Note: This is the CMB-only, foreground marginalised version of the likelihood. The likelihood refers to the deep data as dxd and the wide data as wxw.

ACT DR6 PP

Paper(s):

M. S. Madhavacheril, F. J. Qu, B. D. Sherwin, N. MacCrann, Y. Li et al. (ACT Collaboration)

F. J. Qu, B. D. Sherwin, M. S. Madhavacheril, D. Han, K. T. Crowley et al. (ACT Collaboration)

Type:

Lensing power spectrum measurement (\(\phi\phi\))

Website:

Github

Short cut(s):

candl.data.ACT_DR6_Lens, candl.data.ACT_DR6_Lens_and_CMB

Latest version:

v0

Note: this data set uses the lensing power spectrum in \(\kappa\kappa\). For the ACT + Planck lensing combination see also Carron, Mirmelstein, Lewis 2023. Use candl.data.ACT_DR6_Lens when only working with lensing data, use candl.data.ACT_DR6_Lens_and_CMB when combining lensing and primary CMB data.

Adding Data Sets

If you wish to install data sets separately from the code, please download the desired folders individually from the GitHub repo. You can place these wherever you like. It simply suffices to point to the .yaml file of a likelihood to initialise it. If you wish to build your own data sets, please consult the information here.
