First house related to place of birth
Lagna is dependent on place of birth, whereas planet degrees are independent of it, because they are computed for the centre of the earth. Ephemeris shows planet degrees for a given time zone like IST. So the time of birth must be converted to IST to use such tables. But Lagna must be computed for the place of birth only, because changing the place, say from London to Delhi, will create an error of 5 ½ hours later in U.K. similarly other signs also rise 5½ hours later there. Accuracy of the results computed can be verified by checking that Sun has to be in 10th house at noon, in 1st house in the morning, in 7th house in the evening and in 4th house at midnight. This is irrespective of the place of birth.
