P (band)

P was a short-lived American alternative rock band formed in early 1993 by Butthole Surfers frontman Gibby Haynes (vocals), actor Johnny Depp (guitar/bass), actor Sal Jenco (percussion), and songwriter Bill Carter (guitar/bass).

History

The band performed their first show at the Austin Music Awards in 1993 and released their eponymous debut album on November 21, 1995 under Capitol Records. It was reissued on May 8, 2007 under Caroline Records. They often played the odd gig at The Viper Room, of which Depp used to be co-owner. One of these gigs was played on October 30, 1993, where the lineup included Flea of Red Hot Chili Peppers. Haynes, along with other members of the line-up that night, was a good friend of actor River Phoenix. While the band were in the middle of their song "Michael Stipe", which includes the lines "I'm glad I met old Michael Stipe, I didn't get to see his car. Him and River Phoenix were leaving on the road tomorrow" and "but we didn't have a part, not a piece of our heart, not Michael, River Phoenix or Flea or me," Phoenix (unbeknownst to the band at the time) was outside the venue having seizures on the sidewalk. Phoenix died in the early hours of October 31 of heart failure brought on by an overdose of cocaine and heroin.

Shot grouping

In shooting, a shot grouping, or simply grouping, is the placement of multiple shots on a target, the shots taken in one shooting session. The closeness of the grouping, the nearness of all the shots to each other, is a measure of the accuracy of a weapon, and a measure of the shooter's consistency and skill.

Uses of the term

For firearms that shoot one round at a time, a shot grouping can be used to measure the accuracy of the system comprised out of weapon as well as the precision and uniformity of the ammunition by fixing the weapon into position on a test mount, and aiming it at a target. Multiple shots using rounds from same type and batch are fired to observe how the weapon groups the shots. If a person holds the weapon and shoots it, the grouping measures the combination of the person's skill and the weapon's accuracy.

In shotgun shooting, the grouping is also called the pattern. The pattern is the spread of shot from a single shotgun shell, measured as the smallest circle containing all the shots on the target. The barrel of a shotgun is designed to deliver a wide or narrow grouping, depending on the expected use. Shooting at close range indicates a cylinder bore barrel to deliver a wide grouping, while for hunting at longer distances such as 50 yards or meters, a choke is recommended for a tighter grouping.

Stratigraphic unit

A stratigraphic unit is a volume of rock of identifiable origin and relative age range that is defined by the distinctive and dominant, easily mapped and recognizable petrographic, lithologic or paleontologic features (facies) that characterize it.

Units must be mappable and distinct from one another, but the contact need not be particularly distinct. For instance, a unit may be defined by terms such as "when the sandstone component exceeds 75%".

Lithostratigraphic units

Sequences of sedimentary and volcanic rocks are subdivided on the basis of their lithology. Going from smaller to larger in scale, the main units recognised are Bed, Member, Formation, Group and Supergroup.

Bed

A bed is a lithologically distinct layer within a member or formation and is the smallest recognisable stratigraphic unit. These are not normally named, but may be in the case of a marker horizon.

Member

A member is a named lithologically distinct part of a formation. Not all formations are subdivided in this way and even where they are recognized, they may only form part of the formation.
