Data for: FRB Line-of-sight Ionization Measurement From Lightcone AAOmega Mapping Survey: the First Data Release

The FLIMFLAM Survey is a spectroscopic survey that targets at foreground galaxies of 10 localized Fast Radio Bursts (FRBs) with z<0.4. Each FRB field has a folder, which includes a CSV database file containing galaxies within 1 degree from the FRB and a folder of selection function. These galaxies are collected from the public available image surveys catalogs which are described in Table 2 of the FLIMFLAM DR1 paper. The selection function folder contains a HDF5 file of angular selection function and a TXT file of radial selection function. The description of the columns in the database, angular selection function and radial selection function files are as follows: Database File Name [N]_FRB[xxx]/FRB[xxx]_DB.csv where [N] = [0, 1, …, 8] and [xxx] = FRB name Data Specification Column Name Unit Default Value Data Type Description [ImageSurvey]_objid dimensionless NA Integer Object ID from [ImageSurvey] [ImageSurvey]_[Band] AB magnitudes NA Float [Band] band Kron (1980) magnitude from [ImageSurvey] [ImageSurvey]_[Band]_err AB magnitudes NA Float Error in [Band] band Kron (1980) magnitude from [ImageSurvey] FLIMFLAM_ID dimensionless NA Integer Unique object ID AAOmega_survey dimensionless NA String Target for Wide or Narrow survey AAOmega_ID dimensionless NA Integer Object ID used in AAOmega observation AAOmega_rmag AB magnitudes NA Float Dereddened r band magnitude used in AAOmega observation AAOmega_target dimensionless NA Bool Whether it is an AAOmega target AAOmega_observed dimensionless NA Bool Whether it has been observed with AAOmega [NARROW-8m]_ID dimensionless NA Integer Object ID used in [NARROW-8m] observation [NARROW-8m]_rmag AB magnitudes NA Float Dereddened r band magnitude used in [NARROW-8m] observation [NARROW-8m]_target dimensionless NA Bool Whether it is a [NARROW-8m] target [NARROW-8m]_observed dimensionless NA Bool Whether it has been observed with [NARROW-8m] ra degrees NA Float Right Ascension dec degrees NA Float Declination z dimensionless NA Float Redshift ZQ dimensionless NA Integer Redshift Quality. 1 to 4 represent redshifts from low to high confidence. z_source dimensionless NA String Redshift source Note: [ImageSurvey]: The Image Survey where the photometry data is collected. [ImageSurvey] = SDSS, 6dF, 2MASS, DES, Pan-STARRS or DECam (DECam actually refer to DELVE, but since it uses DECam photometric bands, we use the camera name instead of the survey name) [Band]: The corresponding band of the magnitude (or error) [NARROW-8m]: The NARROW-8m spectrograph used in this field. [NARROW-8m] = DEIMOS, GMOS or LRIS Angular Selection Function (ASF) Table Name [N]_FRB[xxx]/Selection Functions/FRB[xxx]_ASF_[SurveyName].hd5 where [N] = [0, 1, …, 8], [xxx] = FRB name and[SurveyName] = [‘SDSS’, ‘6dF’, ‘FF’] Table Description Angular Selection Function (ASF) is the completeness of a given spectroscopic survey as a function of the spherical coordinates RA & Dec. The ASF is computed separately for every spectroscopic survey, which data is used in a given FRB field. Data Specification Group 1: SKY_RADEC Column Name Unit Default Value Data Type Description RA degrees NA Float Right Ascension DEC degrees NA Float Declination RA_rotated degrees NA Float Right Ascension after rotation DEC_rotated degrees NA Float Declination after rotation Weight dimensionless NA Float Angular selection function (Completeness) Group 2: ARGO_XYZ Column Name Unit Default Value Data Type Description X Mpc/h NA Float Cartesian X coordinate in ARGO box Y Mpc/h NA Float Cartesian Y coordinate in ARGO box Z Mpc/h NA Float Cartesian Z coordinate in ARGO box Weight dimensionless NA Float Angular selection function (Completeness) Note: The FRB is rotated to RA=0, DEC=0 after the rotation mentioned in Group 1. More details (including the resolutions and ARGO box parameters) refer to “readme_ASF.txt” in each FRB selection function folder. The ASF and RSF only calculated for FRB fields used for baryon distribution analysis, hence are not calculated for 20190520B and 20210117A. Radial Selection Function (RSF) Table Name [N]_FRB[xxx]/Selection Functions/FRB[xxx]_RSF_[SurveyName].txt where [N] = [0, 1, …, 8], [xxx] = FRB name and [SurveyName] = [‘SDSS’, ‘6dF’, ‘FF’] Data Specification Column Name Unit Default Value Data Type Description Dist Mpc/h NA Float Comoving distance from the observer fr dimensionless NA Float Radial selection function
