This cycle included two nutrient injections, which occurred at: Injection MMT Local Lander Time UTC 1 3043010 34/06:50:52 1976-10-08T18:05:35 2 3394310 38/05:47:31 1976-10-12T19:40:35 Carriage-Return Line-Feed 9 0 93 temperature 1 1 ASCII_Real 6 deg C Temperature of Labeled Release head-end assembly sensor given in degrees celsius. mars_mission_time 2 8 ASCII_Integer 9 seconds Mars mission time (MMT) is the number of seconds past midnight of Sol 0 (day of landing). Mars mission time is the primary time system used by the Labeled Release experiment. Additional time fields in this dataset are derived from the Mars mission time. native_time 3 19 ASCII_String 12 Native time is the local lander time given as a sol number followed by hours, minutes, and seconds past local midnight on that sol. A sol is a martian solar day with Sol 0 as day of landing. Native time is computed from Mars mission time assuming that a sol is 88775.241 seconds. observation_time 4 33 ASCII_Date_Time_YMD 19 The UTC date and time of a given measurement. Observation time was computed from Mars mission time. hours_from_first_injection 5 53 ASCII_Real 9 hours This field gives the measurement time as hours since the first nutrient injection. Values are expressed as decimal numbers. Negative values indicate times before the nutrient injection. This field is computed from Mars mission time. hours_from_second_injection 6 63 ASCII_Real 9 hours This field gives the measurement time as hours since the second nutrient injection. Values are expressed as decimal numbers. Negative values indicate times before the nutrient injection. This field is computed from Mars mission time. sols_from_sol_34 7 73 ASCII_Real 8 This field gives measurement time in terms of the number of sols since the start of Sol 34 (i.e., near the start of the measurement sequence). Values are expressed as decimal numbers. This field is computed from Mars mission time assuming the length of a sol is 88775.241 seconds. delta_mmt 8 82 ASCII_Integer 6 seconds The number of seconds between the current measurement and the previous one. This field is computed as the difference in Mars mission time between the current and previous measurements. Values greater than 960 seconds may indicate a data gap. observation_note 9 90 ASCII_String 1 This field is used to note possible anomalous temperatures. This field contains an 'A' if the temperature is more than four standard deviations from the mean value of the surrounding 100 temperature measurements. vl2c2ht.lbl 0 PDS3 Original PDS3 label.
