Data model: platePlans

General description: This file is the master file for tracking what plates are to be designed. It is to be edited only by the Plate Designer, at the request of the Survey Coordinator and the survey teams. For each plate, it describes what designs it is meant to be based on and what the observing conditions to assume are.

Naming convention: platePlans.par (there is only one such file)

Approximate size: up to 1 Mbyte.

Required column names for PLATEPLANS named structure:

• plateid (int32): integer identification number for each plate; each piece of metal we drill is meant to have a unique plateid
• designid (int32): design identification number that this plate should use; multiple plates can be based on the same design, but have aspects of the observing conditions that vary and require the holes to be drilled differently
• locationid (int32): identification number for the "location" of the plate and design; meant to signify that there is some relationship between the plates that have the same "locationid"
• tileid (int32): tile number for SDSS-I and -II; set to -1 for SDSS-III plates
• plateDesignVersion (string): version string for plateDefault file name
• ha[6] (float32): hour angle that each pointing should be drilled for (deg)
• temp (float32): temperature at the telescope to be drilled for
• epoch (float32): epoch to assume when accounting for proper motions
• racen (float64): right ascension of plate center, in J2000 deg
• deccen (float64): declination of plate center, in J2000 deg
• survey (string): what survey is this plate associated with? (e.g. "marvels_pre", "marvels", "segue2")
• programname (string): program name within given survey
• drillstyle (string): what instrument is this plate meant to be drilled for? (e.g. "sdss", "marvels", "boss", "bright")
• rerun (string): rerun(s) to use when accessing SDSS data through sdss_readobj (can be multiple separated by spaces)
• platerun (string): name of drilling run this plate is associated with
• chunk (string): targeting chunk number (usually the same as platerun for SEGUE-2 and MARVELS; set independently for SDSS-I, -II, and BOSS)
• name (string): a name for the plate (for convenience, if desired)
• comments (string): any comments on the plate
