Online Dopset Tool

Observing spectral lines with the EVLA-VLA transition system requires some care in setting the sky frequencies. See the recommendations for Doppler tracking using the transition system.

This tool, the Online Dopset Tool, can be used to calculate absolute frequencies for observing with the VLA-> EVLA transition system. For other guidance related to observing with the VLA->EVLA transition system, please go here .


     Right Ascension (J2000):    Hours      Minutes      Seconds  

     Declination (J2000):    Degrees      Minutes      Seconds  

     line rest frequency (MHz):   

     velocity (km/s):       Frame:    LSR      Heliocentric      Type:    radio      optical  

     LST day:       Hours      Minutes      Seconds
