DRPALL File

Name: drpall-[version].fits

This is the final summary FITS binary table for the MaNGA Data Reduction Pipeline (DRP). It merges together information taken from mangacore (the repository containing all MaNGA metadata), and various header information taken from the output MaNGA cubes. It contains no actual spectra from MaNGA cubes, but all of the information required to find a given set of spectra. It can be used to search for galaxies matching a given set of selection criteria. The naming convention is drpall-[version], where [version] is the version of the pipeline used to produce the file. This file is loaded into CASjobs system.

The Data Model for the drpall file can be found here.

In particular, the DRPALL file provides two identifiers for MaNGA targets: MANGAID and PLATEIFU.

PLATEIFU is composed of the plate ID and the IFU DESIGN ID in the format of “PLATE-IFUDSGN”. It uniquely identifies an observation of a target. The same object drilled on two different plates will have different PLATEIFUs. This is analogous to the way of using PLATE and FIBERID to identify targets in the original SDSS spectroscopy survey.

MANGAID is composed of a catalog number and an object number with a hyphen in between. Within the same input catalog (e.g., the NSA v1_0_1 catalog), it uniquely identifies each object. The same galaxy from the same catalog always have the same MANGAID. MANGAID is in the format of “CatalogID-LineNumber”. The number before the hypen is the ID of the catalog. For instance, the NSA v1_0_1 catalog has a catalog ID of 1. The number after the hyphen is the 0-indexed line number of the object in that catalog. For example, MANGAID ‘1-113567’ is the 113567th (0-indexed) object in the NSA catalog. If the same galaxy appear in two different input catalogs (e.g., the NSA catalog and the input catalog of an ancillary project), it could have different MANGAIDs.

For the commissioning plates for MaNGA (P-MaNGA), the galaxies are selected from an older version of the NSA catalog, which has a catalog ID of 12.
