(This information is also available in the drupal FMSsubsystem area: https://drupal.star.bnl.gov/STAR/subsys/fms/database/calibration)

The following datasets (with names) are in the database:
St_fmsGain ("Calibrations/fms/fmsGain")
St_fmsGainCorrection ("Calibrations/fms/fmsGainCorrection")
St_fmsLed ("Calibrations/fms/fmsLed")
St_fmsLedRef ("Calibrations/fms/fmsLedRef")
St_fmsPi0Mass ("Calibrations/fms/fmsPi0Mass")
St_fmsRec ("Calibrations/fms/fmsRec")

fmsGain and fmsGainCorrection are the original calibrations inherited from the FPD.
For the FMS:
Large cells, north -> detectorId=8
Large cells, south -> detectorId=9
Small cells, north -> detectorId=10
Small cells, south -> detectorId=11

The channels are counting from near-beam to outside and bottom up.
Large cells are arrays of 17x34, small cells are 12x24.
The corners and central holes are included in the channel count, i.e. these entries have gain=0.

$STAR/StDb/idl/fmsGain.idl

struct fmsGain
{
    octet detectorId;     /* DetectorId */
    unsigned short ch;     /* Ch 1-578 */
    float gain;     /* gain GeV/ch */
}; 

$STAR/StDb/idl/fmsGainCorrection.idl

struct fmsGainCorrection
{
    octet detectorId;     /* DetectorId */
    unsigned short ch;     /* Ch 1-578 */
    float corr;     /* gain correction factor */
}; 

The following datatables are not indexed. They are only used for the FMS.
The BLOB arrays follow the same order as the channels for the gains (starting with 0 instead of 1, obviously).

};

fmsRec contains parameters for the cluster and photon reconstruction, which have previously been hard coded or stored in local files. These parameters are not likely to change, but have been moved into the database for consistency and backwards compatibility.
