eLMS: fmeng
Applications that have FM related engineering data will have data in this table. The key to this table is lms_application_id using application as the primary table. In addition, if applist_fm/eng_data = 'Y', then there should be an FM engineering record in this table.
NOTE: This information may not be authoritative for the facility that the FCC had actually granted, but in most cases, what was asked for is what was granted. Despite the data errors in FCC LMS raw data, especially on LPFM facilities; the information in the FCC released raw data reflects the granted parameters. This table only appears on records that involve FM engineering (MOD, L2C, CP). Geographic coordinates in LMS are NAD83.
This data is added at the time the application is filed. When the application is granted, the data is updated based on the information from the construction permit or license authorization.
