The NTP Version 3 daemon currently supports several different radio, satellite and modem reference clocks plus a special pseudo-clock used for backup or when no other clock source is available. Detailed descriptions of individual device drivers and options can be found in the Reference Clock Drivers page. Additional information can be found in the pages referenced there, including the Debugging Hints for Reference Clock Drivers and How To Write a Reference Clock Driver pages. ...

... Data extracted from CCD frames may be accompanied by error estimates, which can be used in determining weights in the general solution. These should be in the same intensity units as the data in the SIGNAL column. ... The column label for estimated errors is ESTERR. This column should not be used for ordinary photometric data (i.e., do not put estimates of ``photon noise'' here). ... If the data were expressed as magnitudes (column RAWMAG), any error estimates should also be in magnitudes. ...

... Are reference Transfer Functions available at various colors? ... A: Currently, all but one of the available reference Transfer Functions are for B-V=0.5; there is one file for the PUPIL filter for B-V=1.5. There are two special calibration programs for Cycle 5 which will provide reference Transfer Functions for the CLEAR (F583W), PUPIL, and NEUTRAL DENSITY (F5ND) filters for targets of three color indices ranging from approximately B-V=0.0 to around B-V=1.75 at the center of the field of view. ...
