Narrative:
Inbound to mslp we were assigned atuma 1K arrival with ILS DME Z runway 07 transition. The common fix at the transition point is astor. The STAR shows astor at 2;000 [feet]; but this ILS has astor at 3;000 [feet]. We manually changed the approach to match the STAR with astor at 2;000; believing this was ok as astor is over the ocean. Prior to passing 10;000; we inquired about the astor altitude and ATC informed us that astor was to be crossed at 3;000. We had time to re-enter the approach and modify the STAR altitude well before it became an issue; but it was a fair bit of FMC programming to be doing in sterile cockpit. Not ideal when descending to an airport neither of us were very familiar with. Note that both the atuma 1K and atuma 1L show astor at 2;000. ILS DME Z has astor at 3;000; and the ILS DME Y has astor at 2;300. None of these combinations match up at astor.

Title: Air carrier Captain reported noticing a discrepancy on a GPS point that has different altitudes on MSLP airport STAR and approach plates.
Narrative: Inbound to MSLP we were assigned ATUMA 1K Arrival with ILS DME Z RWY 07 transition. The common fix at the transition point is ASTOR. The STAR shows ASTOR at 2;000 [feet]; but this ILS has ASTOR at 3;000 [feet]. We manually changed the approach to match the STAR with ASTOR at 2;000; believing this was ok as ASTOR is over the ocean. Prior to passing 10;000; we inquired about the ASTOR altitude and ATC informed us that ASTOR was to be crossed at 3;000. We had time to re-enter the approach and modify the STAR altitude well before it became an issue; but it was a fair bit of FMC programming to be doing in sterile cockpit. Not ideal when descending to an airport neither of us were very familiar with. Note that both the ATUMA 1K and ATUMA 1L show ASTOR at 2;000. ILS DME Z has ASTOR at 3;000; and the ILS DME Y has ASTOR at 2;300. None of these combinations match up at ASTOR.
