MULTI-PARTNER PROGRAM (MPP)• MPP is a science program that multiple Partners/Associates (≧ 2)
participate in with PI/Co-PI’s.
• MPP can be any of Normal Program, Intensive Program or Large
Program.
• The number of nights are taken from each Partner/Associate’s
PGT in proportional to the number of PI/Co-PI’s.
• Partners/Associates that participate in a MPP must have enough
PGT and a contract of partnership until the completion of theMPP.
• In order to promote collaborations among Partners/Associates,
up to 5 nights per semester may be reserved from the open-use
time to assign buffer nights to some highly ranked MPP’s in caseof loss of their telescope times due to bad weather, etc. (SACrecommendation)

TWO CATEGORIES OF PARTNERSHIP• Subaru Partner (SP): SAC

(2019.9.5)• Access to Normal, Intensive, Large Programs, and future SSP (aFer PFS).
• Can apply for MulK-Partner Program (including Large Program)• ParKcipaKon in decision-making process (TAC and SAC)
• More than 2 M USD in-cash contribuKon per year
• AddiKonal in-kind contribuKons may be accepted up to 25% of their cash
contribuKon• Term ≧ 3yrs

• Subaru Associate (SA):• Access to Normal and Intensive Programs• Can apply for MulK-Partner Program (excluding Large Program)• Observer parKcipaKon in the TAC.
• More than 400 K USD in-cash contribuKon per year
• In-kind contribuKons may not be accepted• Term ≧ 2yrs
*Unit can be any of a country, a multi-country organization, an institute, or a multi-institute consortium.

HOW TO CALCULATE THE NUMBER OF NIGHTS FOR
PARTNER GUARANTEED TIME
• Partner’s guaranteed time (PGT) is allocated to eachpartner/associate based on the fraction of total contributions fromeach partner to the value of Subaru:
Value of Subaru: 20 M USD (~2.2 B JPY), considering the past 20 yrs of operations
Total available nights for science operations: S
Partner/Associate’s contribution (M USD): P
Number of PGT = S * P / 20
Note: Total available nights for science operations (typically ~220-240nights) are calculated as:
S = 365 - (down time + UH time + open-sky time + DDT + engineering)
If S is 220-240 nights and P is 2 M USD, No. of PGT is 22~24 nights7 / yr.
If P is 0.4 M USD, No. of PGT is 4.4~4.8 nights / yr.
Those nights will be roughly evenly breakdown into dark/gray/bright nights.

SUMMARY• Subaru Partner• > 2 M USD /yr in-cash contribution à > 22-24 nights / yr
• Subaru Associate• > 400 K USD /yr in-cash contribution à > 4.4-4.8 nights / yr

• In-kind contribution can be accepted for Partners only, and isadditional and <25% of their cash contribution• We introduce “Multi-partner program” which can be organizedfreely among partners/associates using their own telescope times,
in proportional to the # of PI/Co-PI’s.
• In order to promote MPP, up to 5 nights may be reserved to assignbuffer nights to highly ranked MPP’s in case of loss of nights (SACrecommendation). SAC  
