Bug: Karana name is incorrectly mapped/indexed in Panchang calculation

While validating a chart against three other astrology applications and the classical Karana sequence, I found that the Karana number is calculated correctly, but the displayed Karana name is incorrect.

For this chart:

• Calculated Karana index/number: 47

• Expected Karana: Taitila

• Currently displayed in the application: Bava

The screenshot also confirms that Karana 47 corresponds to Taitila, followed by 48 Garaja.

Expected Result

When the calculated Karana number is 47, the application should display:

47 – Taitila

Actual Result

The application displays:

Bava

Suspected Issue

This appears to be a Karana name lookup/indexing problem, rather than an astronomical calculation issue. The Karana number is correct, but the name may be fetched from the wrong array position—possibly due to a zero-based versus one-based indexing mismatch.

Kindly review the Karana sequence mapping and correct the name associated with index 47.
