 Additional Notes:
  1. Only is considered a comment if the line starts with '\*'.
- 2. Calibration takes samples at its current location (which should typically be 'cal') and uses those to determine the shape of the band-pass filter and eliminate it from the calibrated spectra.  Calibration should therefore by done against a non-source object of known noise temperature.
+ 2. Calibration takes samples at its current location (which should typically be 'cal') and uses those to determine the shape of the band-pass filter and eliminate it from the calibrated spectra.  Calibration should therefore by done against a non-source object of known noise temperature. The exat behavior is dependent on the type of calibrator programmed in the config.
  3. Unlike the previous SRT software, 'quit' both stows and quits (ends the daemon process).  After this is done, it will be necessary to restart the daemon process from command line or via the Dashboard 'Start Daemon' button.
  4. Currently, three different file types are supported, and the type used is determined by the file extension of the name given.  FITS (Calibrated Spectra) is used when the file ends in '.fits', rad (Calibrated Spectra) is used when it ends in '.rad', and Digital RF (Raw I/Q Samples) is used when the name lacks a file ending.  If no filename is provided, Digital RF will be used with an auto-generated name.  In order to use rad or FITS with an autogenerated name, use "\*.rad" or "\*.fits" respectively.
  5. The names used for pointing at objects are set by the 'sky_coords.csv' file, which is further documented in the config folder portion of the docs.  By default, 'Sun' and 'Moon' are already loaded.
+ 6. calon and caloff commands are valid only for antennas with some form of noise injection or dicke switching.
+ 7. ICRS coordinates, expects decimal degrees for both Ra and Dec
+ 8. will accept standard iso formatted utc timestamp to any precision
