Data model: ancillary-targets

General description: Input target list from an ancillary team. Should be accompanied by a descriptive text file ("ancillary-targets.descr" for example). The full list of which files are actually used for bosstile is given by the ancillary-bossN file.

Naming convention: ancillary-targets.par or ancillary-targets.fits

Approximate size: variable

File type: Yanny or FITS

Read by products: bosstile

Written by products: variable

Required header keywords: none

Required column names:

• ra (float64): right ascension of source, J2000 deg
• dec (float64): declination of source, J2000 deg
• sourcetype (string): type of source
• priority (int32): priority value; lower numbers will be favored; must be greater than 0
• fibermag[5] or fibermag_u, fibermag_g ... (float32): 3-arcsec fiber magnitude (first option if FIBERMAGTYPE equals ARRAY, second if it equals COMPONENTS in the appropriate line of the ancillary-bossN file

Optional column names:

• propermotion (float32): amplitude of proper motion in arcsec/century (CAS-style); used if PMTYPE equals ANGLE in the appropriate line of the ancillary-bossN file
• angle (float32): deg E of N of direction of proper motion in arcsec/century (CAS-style); used if PMTYPE equals ANGLE in the appropriate line of the ancillary-bossN file
• pmra (float32): proper motion in arcsec/yr in RA direction (E positive); used if PMTYPE equals COMPONENTS in the appropriate line of the ancillary-bossN file
• pmdec (float32): proper motion in arcsec/yr in Dec direction (N positive); used if PMTYPE equals COMPONENTS in the appropriate line of the ancillary-bossN file
• epoch (float32): epoch of given RA and DEC, in years (used as zero-point when correcting for proper motions); either this or "mjd_r" should be set if proper motions are supplied
• mjd_r (float32): epoch of given RA and DEC, in modified Julian date days (used as zero-point when correcting for proper motions); either this or "epoch" should be set if proper motions are supplied
• run (int32): SDSS drift scan run number target came from (if SDSS-based)
• camcol (int32): SDSS drift scan camcol number target came from (if SDSS-based)
• field (int32): SDSS drift scan field number target came from (if SDSS-based)
• rerun (int32): SDSS photometric rerun number of run target came from (if SDSS-based)
• id (int32): id number within SDSS field of target (if SDSS-based); used if IDFIELD equals ID in the appropriate line of the ancillary-bossN file
• obj (int32): id number within SDSS field of target (if SDSS-based); used if IDFIELD equals OBJ in the appropriate line of the ancillary-bossN file
