## STANDARD REFRACTIVE MODULUS GRADIENTThe uniform variation of refractive modulus with height above the earthâ€™s surface which is regarded as a standard for comparison. The gradient considered as normal has a value of 0.12M unit per meter. The M unit is the unit in terms of which the refractive modulus is expressed. |
