dRV

tayph.dRV(dp)

This program calculates the change in radial velocity in km/s for the planet in the data sequence provided in dp, the data-path. dp starts in the root folder,i.e. it starts with data/projectname/, and it ends with a slash.

Example: dv=dRV(‘data/Kelt-9/night1/’) The output is an array with length N, corresponding to N exposures. The change in radial velocity is calculated using the first derivative of the formula for RV, multiplied by the exposure time provided in obs_times. The answer is provided in units of km/s change within each exposure.
